Very nice, thanks for posting.

Anyone know what other gobys/stiphodons there are which can be kept at normal tropical temperatures without additional flow?

I wondered about Stiphodon atropurpureus/semoni

To be honest, and I'll @Paddyc here too, what I initially said was a bit muddled.   

The producing of more CO2 was badly phrased here.  Adding greater flow of air won't produce more CO2 but release more of the potential of the CO2 amount already in the water.  The potential is reached when the CO2 is mixed with the water to form carbonic acid (H2CO3 - so wish subscript worked for me).  As it's an acid (in normal atmospheric conditions it has a pH of around 5.65) this reduces the overall pH value.  This is the usual state of a normal aquarium and you can't increase the total of CO2 by adding more air.   Too high a water movement can have the adverse effect of raising pH more because CO2 exchange at the surface doesn't allow it to change into carbonic acid.  Usually this will top out at around pH 8.4.

For plants adding CO2 to achieve a constant pH value would require a controlled system such as a pressurised CO2 kit.  For example to achieve a pH of 7.4 in water with KH of 4 based solely off carbonate (CO3) would need CO2 to be at 4.8 ppm but that's not really what the CO2 kit is trying to achieve.  To get the most out of CO2 in water for your plants the kit is trying to get you to 30 ppm which in the above controlled example would lead to a pH of around 6.6.  At 30 ppm the CO2 levels are considered optimum for the plants.  Also carbonic acid isn't the only acid in your tank which is why drop checkers aren't calibrated against the tank water but a separate liquid usually at 4KH.  The actual pH when the CO2 is added may turn out a little lower.

Thanks @Sue I am 'little kid level' excited about getting a couple of these!! 

Can I just check what water temperature you have yours at and what you feed them? I was considering Soilent Green from what I have read online...

OMG @Matt Soylent green!!!!! Do you know what that's made of?

Very recently realised that I lived within driving distance of the on-line aquatic plant retailer that I'd previously purchased from. I took a drive to the Aquarium Gardens store this morning and have realised that I'm as bad with plants as I am with fish.

My timing is also quite awesome, as the owner said they have an aquascaping demonstration by George Farmer on Thursday evening, so will be going to that too. 

I think I killed a fish last week 

Last time I did a water change, I also cleaned the media in one filter. Eheim biopowers have a clip on the back which slots into a bracket. It was a bit fiddly getting the filter back on the bracket last week.

I've just done a water change. When I put the filter back last week, the mini spray bar wasn't positioned correctly so today I unhooked the filter to move the bar and a dead fish floated to the surface of the water. It was a long dead, flattened fish. The fact that it was flat and hadn't been eaten makes me think I trapped it when I put the filter on the bracket last week. It had been there a fair while as it stank.
I think it was a stiphodon because the eyes were close together on top of the head, and these fish do cling to the glass or anything else solid - like a filter bracket.


So be warned, if you have a filter that clips into a bracket, make sure there are no fish in it after cleaning the filter.

Sorry to hear about your fish @Sue
Some fish are more prone than others to various types of accident due to behavioural characteristics, and when you consider how frequently filters are moved, sometimes it feels like it's only a matter for time before these accidents happen, however careful we are.
 

They haven't been breeding replacements, have they? Just to confuse you of course 

@marquismirage my tanks are all planted, but far from aquascaped. As a general rule my focus is on the fish, and the plants are there to create hiding places for the fish, help with the water, and make the tank look ok.
It would be positively rude not to watch an expert in action, less than 15 miles from home, for free (not counting how much I've spent on plants this year  )
Don't expect a marked improvement in my tanks though.
