Hello, I just picked up a 2'' clown knifeand a 2'' silver arowana and my dad got 2 6'' channel catfishes. Thanks Nate from MA. Now here is some ?'s for you clownknife experts to answer for me. Now I have the clownknife with 2 bala sharks, 2 ID sharks, and a 2'' clown knife in the 20 long grow out tank. Will he be allright with these guys?? Also what should I feed the ck???Anyone have pics of their smaller sized cks?? I'll post some pics soon..
