CK and Oscar Compatibility

They will be fine as long as one can't get the other in it's mouth. Remember that both have large mouths, especially the CK.

Wouldn't you eventually need a larger tank though-if I read the sticky correctly it stated that CK get to 39 inches and if that is the case a 120 gallon is too small-I had one in my 240 gallon and got 18 inches within a year.

I had 2 4" Ck's in a 55g corner with 2 4" O's and everything was good until the CK's got about 6" then they started getting aggressive come feding time, so now they're in seperate tanks until I get my 220 next month. I noticed when I seperated them (about 6 mos ago) the growth rate sped up. Now my CK's are 10" and the O's I had witht them are 8-10"... We'll see how things go in this 220 when I put them together...
