The ammonia levels in my cycling 60l (16 US gallon) tank have plummetted in the last couple of days
The nitrites can't be far behind, it's time to start planning my fish.
I want everything to be small, so I'm thinking;
3 Neon Tetras
2 Cardinal Tetras (the should school with the neons?)
4 White Cloud Minnows
1 Corycat.
I make that 19", which is a little overstocked according to the 1" per gallon rule mentioned on this forum a lot, but I can't see an easy way to avoid this without causing schooling issues. Surely if I change water more frequently, and also, won't smaller fish cause less bio load than larger fish as they are smaller in 3 dimensions, not just length? Tetra seem to advise 1cm/litre, so 60cm or 24" of fish.
With less tetras and minnows, they won't school, and I really need a corycat to add variety and do some cleaning of the sand.
So;
Are my fish compatible?
Are there too many fish, or is tetra's advice ok?
Are there too few of one species? Will they school, will the corycat get lonely?
