Clowns grow large - Eventually. They are pretty slow growing, but yes, eventually they are going to grow out of that tank. From my 40g tank, they go into my 75g tank, and if they get too large for that, then it'll be back to the lfs. By that time I will have had several years of their company (and antics) to enjoy.rbishop said:Shouldn't he also stay away from the clown loaches from a growth standpoint?
