Thanks guys - I am hoping to get some small Anubias to plant over the twiggy wood in that corner - what you cant appreciate in the pic is though the amount of little caves in that structure.
Alex - I am getting a trio for this tank, I have a large grain sand in there but its nice and smooth just cheap stuff from Maidenhead but its still smooth and more natural than play sand - plus I didnt want to get a full sack of play sand for this little tank haha there is only a handful in there of sand! As for tank mates due to the low temperature of these fish your choices are quite limited but they do seem to go perfectly with Celestial Pearl Danios there are about 3 other schooling species that you can go for as an alternative mainly most micro danios as opposed to micro rasbora who prefer much higher temperatures. There are about 3 species of catfish that would work, 1 very rare gourami and a few loaches. But thats if its being kept biotope correct I would suspect that some American fish would work well with these particularly some cory species that prefer to be kept at lower temperatures.
I have to admit I have been caught utterly off guard by their temperature requirements and as a result I would give this advice on them - by all means get them for the little tank they are perfect freshwater nano fish but with regards tank mates you have to research thoroughly before purchase because the tank mates need to follow all these requirements (though one or two are optional)
- Need to thrive in 20-22 Celsius
- Need to stay under 2 inches max
- Need to be calm enough not to over power the badis - ie. avoid larger species of danios
- Should not be too distracting from the badis
Goat - need to pick your brains, can you think of any Asian Killi fish that could work in this tank preferably not annual - though that could work? And also any small rainbow fish? All the rainbows Ive come across so far have been higher temperatures but I am sure I have heard of some that do well in low temps?
Also how do cherry shrimp do in lower temperatures? Thinking of some cherry shrimp?
Elise - Are yours colouring up any more? Also not sure if we can get any more

Last time I looked they are down to the last one haha!
