Pacus are technically suppose to be herbivores, but I've seen them go for feeders before. So my answer is yes...it can eat a smaller fish. How "large" is the Pacu?
i agree ^ it depends on the size... i've had a 14-16" pacu that has eaten 3-5" cichlids. so i would be careful on the tankmates. i got my pacu already grown out so i had know idea it was that way. . . unfortunate
My pacu decided they were going to eat my 7" freshwater drum..so can they..yes. Tho my pacu do cohabitat with 2 chiclids 3" and 5" and dont bother them at all. For some reason they just decided they didn't like that particular fish
Maybe one's you are familar with....Not all are....Some people actually care Pacu...
I tend to find that my Pacu will not bother other smallers fish-Only when the smaller fish will instigate-Then Pacu will put said fish into it's place in the pecking order...
Pacu does have the ability to eat a smaller fish though......
