I adore clown loaches!! I recently heard they growe slow and it takes about 5 years form them to go from 2" to 6". My LFS sells 1.5" long clown loaches and I was wondering fi trhey would be happy in a 72 glalon sharing the bottem with 12 cories of the same type for a few years. after that, how hard is it to sell them to other people?
