Oh yeah you could do a really nice asian/indio tank with Etroplus canarensis - dats sound awesome as well
cheers for the comments. I hadn;t thought of them bnut have always wnted a spare tank to fill with Boesmani rainbows as I love them, would they be too big and compromise the amount of clowns I could have?
I'll have to check Preacox out see what it looks like
my external is prety pwerful anway but would they benefit from an extra powerhead in there to give a fair amount of water flow for the clowns?
