How small do you want to go? If tiny (15 to 20 mm) would be OK, how about Microdevario kubotai These are green fish from Thailand and Myanmar, so they'd fit 'no more red' and Asia. And they like soft water. They are sold as green rasboras or green tetras.

Thanks @Sue . They look interesting. I will have to do about more research to check that they're not too small to be picked on by my other fish.

I saw them a few months ago and again a couple of weeks ago in the LFS. Both lots are much more the size of neon tetras than as small as Sue's experience - and I've read that this size variation is commonplace on quite a few sites. Incidentally, last time round they were described as 'neon yellow rasboras' although actually luminous green https://www.fishkeeper.co.uk/databank/neon-greenyellow-rasbora-. [The term 'green tetra' may be confusing as there are several which might fit that bill - green-coloured tetras https://www.fishkeeper.co.uk/databank/rathbuns-bloodfin-green-fire-tetra and blue-green-coloured tetras http://www.seriouslyfish.com/species/paracheirodon-simulans.]

Thanks @fcmf for the links. I buy all my fish from my local MA, so it is nice to know that they stock them and also what name they give them.

Presumably there's a big variation in size because there's more than one species that looks the same?

I think I need to go and see them in the fish shop.

They do look attractive option, but I am concerned about their size. I think they should be ok with my shoaling fish - the dwarf rainbows seem to be on the limit of size and my harlequin and espeii rasboras are actually recommended by seriously fish as suitable companions. But if i put celestial pearl danios or axelrodi rasboras (both a similar size) into the CC, I get red warnings about them and both kuhlis and kribensis.

I don't think the kuhlis would be a threat because their mouths are actually really small.  And I don't have kribs yet. Also they live in different parts of the tank, as I understand. But one of the attractions of kribensis is to have something a bit different and bigger than the rest of my fish (as a sort of specimen species). So I'm not sure about going smaller than the espeii rasbora.

Apart from tetras not being Asian fish, any thoughts on penguins, Black neons and x-rays ?

I saw penguin tetra in my LFS last week and was really taken by them, they were tight schoqlers and really beautiful fish  :D. I think they get a bit bigger than xrays/neons though...

Thank you.

Having found this article I will persevere with finding an Asian shoaler!

https://www.practicalfishkeeping.co.uk/blog/articles/2016/11/18/social-acclimation-the-next-thing-in-fishkeeping

It's also made me wary of increasing my existing shoal sizes - of dwarf rainbows and harlequin rasbora! :o

I have penguin tetras in one of my south american tanks. They are great fish, and they hang around in a slightly nose down position, which is a bit different. However, they are relatively large, both in size and personality. They can be a bit boisterous, which can have an impact on other fish in the tank.
I think that your suggestion of finding an asian shoaler makes a lot of sense.  :)

This is looking like a good contender:
http://www.seriouslyfish.com/species/brevibora-dorsiocellata/

I thought it was a recommendation from here, but can't find the comment! Finding it might be the challenge. EDIT: I've just found it on MA website: https://www.fishkeeper.co.uk/databank/emerald-eye-rasbora

I will also have a look at the green rasboras.  ;)

There's loads of ricefish @Matt . :yikes: It's going to take me a while to look through them to find one that's the right size and water conditions. Water hardness might be an issue.

I have good international relations in my tank - x-ray tetras and harlequin rasboras.

The x-ray tetras' daytime is probably split 25% in each of the following modes, from early morning, late morning, afternoon, evening: the males having quite vigorous spats while the female rests elsewhere (and occasionally a harlequin joining in); a female being chased vigorously by all the males, esp through the plants; quiet times when they rest at particular "staging posts" in the tank, usually in the lower third; playing and swimming together with the harlequins, esp in the filter flow, inter-shoaling as though all one species.

The harlequins' daytime is less varied and tends to be split 50%, 25% and 25% in morning, afternoon and evening respectively as follows: quiet times whey they rest at particular "staging posts" in the tank, usually in the upper half; one male harlequin taking possession of the middle 50% of the tank, chasing anyone (irrespective of species) who enters that territory round the tank at speed and into a corner / two males (I think) displaying against each other; playing and swimming together with the x-ray tetras, esp in the filter flow, inter-shoaling as though all one species.

I suspect the afternoon behaviour of the aforementioned harlequin is just unusual, while the spat behaviour was learned from watching the x-ray tetras in which one tries to get involved occasionally.

At night, once the light goes off, there's a bit of re-positioning in which they shoal up with their respective species but a bit of manoeuvring takes place, generally resulting in the x-ray tetras at mid-level and the harlequins in the upper third ie each species slightly higher up than their daytime resting positions.

Thanks fcmf. That is interesting about your x-ray tetras and Harlequins shoaling together. The largest shoal in my tank is a mix of harlequin and espeii rasboras.

I didn't mention rice fish although I have Daisy's ricefish (Oryzias woworae) because their hardness range has 5 dH as their lower end.

I've kept M.kubotai in the past and I'd say mine were the same size as the ember tetras I had in the same tank. The biggest fish I had them with were Apistigramma cacatuoides, and the male is quite a big fish for a dwarf cichlid.

There are 3 types of ricefish on the MA website. One is too small, one needs harder water (Daisy's) than I have and the third needs cooler water.

I'm not sure that I'll succeed finding one that fits my water parameters and size requirements. They also seem to prefer clearer water conditions (all my other fish are black water, preferring higher tannins). Ricefish seem to prefer the clean water of flooded fields.

I'd have to give a massive +1 for Pristella Tetras (X-Ray Tetras), which are probably the favourite fish of mine to date...  I have 12 of them and they seem super peaceful and playful, sometimes shoaling with the Cardinal tetras just for the fun of it...  Great fish indeed and I'd gladly have more of them...  :)

I've just been into my lfs. They had everything on my potential shopping list - except kuhlis.

The neon green rasboras (m. Kubotu) are definitely a very striking fish. Outshone the emerald eye rasboras by a mile. The fish shop had them as a max size of 3cm, which correlates with all the comments about them being a bit bigger than the 15-20mm originally mentioned. Think they are the ones for me. But I'll probably have to re-think the kribensis.

My tank will look very colourful with red, blue and green fish!!

The photo doesn't do them justice. They looked fabulous in the fish shop tank. Looking a bit washed out as they acclimatise in my tank.

Great you got the microdevario kubotai. Hopefully they'll soon colour up in your tank and look as great as / even greater than in the LFS.

I think they may have started colouring up even before I took them out of the bag! But with the lights off and the bag floating next to green Vallis, it was difficult to tell.

But they are definitely neon now. Mr Helen asked if they are bred to be that colour.  ;)

So my tank is now fully stocked because I also bought another 6 each of harlequin and espeii rasboras.

I phoned the fish shop this morning to ask about kuhli loaches and was told that they didn't know when they'd get more in, but they weren't planning to soon. (When I was buying the fish, I chatted some more to the lady and she explained that the way they have the tanks set up, the kuhlis keep escaping through the weir into the giant sump tanks. They can't be treated for any diseases there and getting them out is so stressful it exacerbates the problem. So before she can get any kuhlis in, she has to rearrange the tank pipework and take a tank off the system).

The last couple of days I've been reading up on tank capacity calculations and the effects of plants (as well as the conversations on this forum) and it has been playing on my mind about only having 6 harlies. The harlies and the espeiis shoal together, but I get the impression that the hierarchy is determined a lot by size - which puts all the espeii at the bottom. I introduced 6 harlies and 6 espeiis to my tank when I had one harlie from the previous shoal left. Within a couple weeks one of the large harlies disappeared. I now believe he was the loser of a battle for top spot. So I wanted to increase my shoal, but was worried about doing it. And I didn't want to increase the number of harlies without increasing the espeiis.

So, when I saw that they were all in the fish shop and the harlies seemed rather small, I thought that numbers would be the best way to introduce more and do it at the same time as the microdevario kubotai.

I went into the fish shop on the way to my son's swimming lesson, so I knew it was just for looking. And then he had a snooze in the car so I had a chance to do some number crunching. I realised that I could get the 24 fish if I gave up on getting more kuhlis (and the kribensis).

The m. kubotai are all about 10-15mm with the espeiis being a similar size and the harlies probably about 20mm. So I think I've added about 40cm of fish today (I had calculated I could have up to 60cm, but I think that calc was flawed).

Anyway, adding the new inhabitants has done some very interesting things to the dynamics in the tank. Two or three of the existing harlies were chasing everyone else around - even the rainbows and barbs that are bigger than them and they've not seemed to bother before. So much so that I didn't dare turn on the second light until they all seemed to have calmed down a bit. I am just glad that my tank is so well planted because there doesn't seem to be a shortage of hiding spots. And the large bits of anubias that I cut off the other day and can't yet bring myself to throw away are doing a great job as floating plants breaking up the line of sight. They'll be staying longer!

Are microdevario kubotai considered to be dither fish? I ask because the barbs and the kuhlis seem to have come out more into the open with all the mayhem going on in the top half of the tank.

I don't know how this will all change over the next few days as things settle down, but it is certainly making for interesting watching (and a little unnerving at times). I'm wondering if I'm going to have to get my QT out of the shed tomorrow. :yikes:

A quick Google brought up this definition:
"Dither fish are schooling, mid-water swimming fish that are used to bring hiding fishes out into the open."

I have selected the definition that best fits my understanding of a dither fish. But there were variations on the theme. And something I didn't realise, that it seems to be used a lot in relation to cichlids (as the hiding fish).

You'll have to be patient for photos. It's not easy taking a photo of a 4' tank with small fish where you can see both. Especially when half the inhabitants are experts at camouflage (and there's plenty of opportunity). Also, my phone isn't doing photos at the moment, so I have to be more organised and get a proper digital camera out, hook it up... etc etc

I hope to do a video at some point because the most interesting thing about my tank (imho) is the fish behaviours and interactions. But that requires me to also come to terms with YouTube.

Thanks for that Helen...  I've seen the term a few times and it never sounded like it had much of a logical meaning, with trying to imagine hesitant or indecisive fish or some other such explanation, lol...   ;D

I hear ya on the YouTube thing...  Could do with sussing that one out here, too...

If they have had this effect on your other fish then I would agree they are acting as a dither fish for them. I don't think there are specific dither fish as such. Any fish can act as a dither fish for another fish. There are some like hatchets which make very good dither fish... though this is mainly because they are always at the surface.

Dwarf cichlids can be particularly reclusive if they think they are in danger of predators. Small shoaling fish swimming round above their heads indicate to the cichlids that there are no predators about - the shoaling fish would be #1 targets - so they know it is now safe to come out of hiding. These small shoaling fish are called dither fish.

Thoroughly enjoyed the update on the tank dynamics following the new additions. Keep us posted with updates on how this progresses and, ideally, a video; incidentally, YouTube is actually really straightforward - I was pleasantly surprised at how easy/intuitive it was to use when I first used it a year or two ago (and I'm not at all tech-/IT-oriented).

I don't really have space for another shoal in my tank. I'd love to get more Microdevario Kubotai or something of a similar size, but seeing as they were probably the shortest lived species I've had, they clearly weren't suited to my tank and  I don't think it's fair to get more.

So, after a bit of aspirational fish research (for after my espie rasboras have gone) I found this fish profile on seriously fish.

https://www.seriouslyfish.com/species/puntius-lineatus

I am struggling to find it on the other sites I've looked at (admittedly not loads yet). It is smaller than all the other lined barbs I've seen and wondered if anyone else has come across it?

I have not come across this fish before, either in my on-line researches or in shops. I wonder just how common it is in the aquarium trade. SF does seem to contain a number of rare fish. This is one of its downsides - we find a fish that would be perfect on there but then find it isn't available  :-\
