Hello, I Was Wondering, In a 55 Gallon, could a 10" CK Live With a 2.5" Convict? There are LOTS Of Hiding Places!!
 
Your convict will probably dissapear overnight. Knifefish have larger mouths than you'd expect. I personaly wouldnt risk it.
 
ok. How large would the Convict have to be to go with a 10" CK?
 
Probably about another inch or so, but by that time your CK would have grown too. Is it possible to try a devider and see how they react to eachother first? My RCK is the boss of the tank and doesnt tollerate small fish very well. If he cant eat it, he will terrorize them for life lol.
 
Ok! My Clown Knife Seems to be ALOT More Peaceful then Everyone elses For some reason! He lives with a 2 inch GOURAMI!!!
Thanks For The Help!
 
Oh well if he hasnt eaten that little guy yet, you might be ok. Just keep the ck well fed and keep plenty of hiding spots for the little guys. If worst come to worst - convicts dont cost too much to replace lol. Good luck man. Keep us posted on this one.
 
Upgrade to a bigger tank or get rid of the Clown Knife, they can grow up to 28" and yes it'll eat your convict, especially if you've fed it live food in the past.
 
Um... I Have A 180 JUST FOR HIM! Lol!
 
Once I Move out all my Africans, He Will Have The 180! Oh And BTW, I have 4 CKs!

Have they been together since a young age? Knifefish typically don't tolerate others of the same species once they reach sexual maturity.
