Compatibility Question

Hi Lellynelly,

Seriously Fish is a bit more up-to-date than Thinkfish's Fish Profiles - we do intend to resume updating them soon, though.

Looking at this http://www.seriouslyfish.com/species/sahyadria-denisonii/, it seems that a torpedo barb actually needs a tank twice the length of your bigger tank. It also seems that the rosy barbs http://www.seriouslyfish.com/species/pethia-conchonius/and the angel fish http://www.seriouslyfish.com/species/pterophyllum-scalare/need a bigger tank than they're in too.  How old are each of the fish currently?  They might be alright while very young but you may find problems (health, territorialism) start to set in later on down the line.  If they're very old and the remnants of existing shoals, then it's possible that they may see out their final days where they are if somehow it's not been causing too much of a problem that you've noticed.

You have a few options:
* getting a bigger tank, if you can make the space for it [and provided that all these fish would be compatible with one another - only have a short lunchbreak so unfortunately can't check this up for you just now] - you may pick up a good bargain second-hand
* selling / giving away the fish via a site such as Aquarist Classifieds (which increases the likelihood of them going to a good home with an experienced fishkeeper than selling through generic websites) and re-stocking your tanks with fish more suitable to their current size/capacity

Are either of these a possibility at all? If not, we'll collectively try to figure out what might be for the best, or someone else on here may be able to suggest an alternative.
 

Hi Lellynelly,

I can understand not wanting to interrupt peace and tranquillity once it's been restored.

Great that you have a 120-litre tank - that would be a more suitable home in line with the requirements of the angelfish, the torpedo barb and the rosy barbs. How would you feel about some swapping around? For example, the harlequins and tetras (depending on the type) might fare very well together in the 60-litre tank without any other tankmates, leaving the remainder of the fish in the 120-litre tank along with these new tankmates.

@Littlefish is an expert on swapping fish around between tanks, while @Sue and others have more experience of the other fish and whether they might all get on together. It might just be that a little experimentation is required.

Hi people thanks for your replies. I think I have a solution. I have a 200 litre (4 ft) tank that I bought 18 months ago with the intention of setting up as a marine. But after lots of research I have been in 2 minds as to whether I have the time, finances, or skill to do it, which is why it still stands empty. So my current situation has led me to make the decision to set it up as a tropical. I bought the necessary equipment yesterday and set it running, so it is now happily cycling. Once cycled I will put the angels in there and probably the torpedo.

Good idea.
