HELP!!!

[John maverick]

I added 3 red bellied Pacu into my fish tank with the tinfoil barbs question:does pacu nip or bite larger fish than them?? My tinfoil barbs are getting injured i dont know why
2 pacus are fine because they are smaller compared to my 2 tinfoils and 1 pacu seems to be nipping my tinfoils because he is the same size as my barbs

Sounds possible. I've raised some pacus that have cohabed pretty well but I have heard reports of such behavior. Do you have any other tanks mates(suspects)

 

[John maverick]

NOPE. 1 Goldfish 1 carp 4 iridescent sharks 1 rainbow shark

 

[Wailua Boy]

Rainbow sharks can be nippy but if your seeing the pacu shadowing the tinfoil, your probably right

 

[John maverick]

Ouch,Rainbow sharks only eats algae he never eats fish food he's fine with the tinfoils i Dont know what to do with my pacus

 

[Wailua Boy]

Rainbow sharks can be very territorial and aggressive IME

 

[Wailua Boy]

In a large enough tank possibly adding more pacus could help but they grow so large that usually isnt plausible

 

[John maverick]

I really loved my pacus

 

[John maverick]

Thats the tinfoil barb that is really injured

I bet the tinfoil barbs r attacking each other,fin nipping is more a barb thing,when pacu bite they tend to take whole chunks,I recommend adding a bunch of giant danios as distractions.
