2 tinfoil barbs are chasing each other and 1 barb is chasing the pacu but the barb just wants to touch him not nip the pacu
I think 30-40 gallons?
Picture your pacu in 2 years...(picture not mine), even 300G still small for a full grow Pacu and they are grow super fast. There is a story of a staff working in publish aquarium and they said they can see Pacu growing everyday, it's very noticeable grow rate, I myself kept them before and I can see them gain their size less than a week if keep well fed and good water (double its size from 3 inches to 6 inches less than 2 months). You best bet and a right decision is rehome your pacu right away!I think 30-40 gallons?
