I have 4 clown loaches. The biggest is super fat and about 8". Another is around 7", but not as fat. Then 2 smaller that are 3-4". Funny thing is I bought them all at the same time and they were all the same size. I never see large one's at my LFS. I'm wondering how much the two big ones are worth? I'm starting to think they are getting too big for my tank, it's 55g.
