Spotted Climbing Perch Question

[aweav]

A couple months ago I got a spotted climbing perch (Ctenopoma acutirostre). The guy at the LFS told me he would be fine in my community tank so I thought all would be good. I did a little research later to find out he's supposed to be carnivorous and eat anything little. He is just a little guy right now 1.5", but I was wondering what I should do? Nothing in my tank is smaller than he is now, but after seeing him "yawn" I became very concerned. Should I try to take him back or just wait and see?
Tank specs
60G
5 Buenos Aries Tetras
3 Dwarf Neon Rainbows
2 Bleeding Hearts
1 Red Hooked Met
1 Silver Dollar
1 Black Skirt Tetra
1 Krib
3 Rosy Barbs
2 Angels
2 Emperor Tetras
1 Paradise fish
4 Various Gouramis
1 Rubbernose pleco
1 "tiger striped" Loach
1 Golden Kili (another one he said was safe)

Yeah its a little full but working on getting another tank.
Thanks

He will eventually inhale all your tank occupants except:

5 Buenos Aries Tetras
1 Red Hooked Met
1 Silver Dollar
1 Krib
2 Angels
4 Various Gouramis
1 Rubbernose pleco
1 "tiger striped" Loach
1 Golden Kili (another one he said was safe)

...and the krib and killi could be at risk, depending on how big they are when the Ctenopoma hits 6".

So are they fast growers and I should try to take care of him now or do I have some time to let him grow and see if he becomes more of a problem?

He will grow quickly to about 3½"-4", at which time he will be a threat to many of your fish.
