How soon will I have Nitrite problems Jon?
True, but I think with clown loaches you have several years before you have an issue with their potential size.
I've had a pair going on 5 years now and they aint exactly busting the seams apart of their 30g just yet... It is pretty cool to see the big ones though, we have a an LFS here that has a display with two or three trout sized clowns. (I think these are MY favourite FW fish.. or possibly loaches in general, at least.)
