So I went in to pick up my two 15" red belly pacu for my pond on Tuesday from the LFS I go to alot and I ended up picking up a 3" ornate bichir also. Paid 40 for him so not that bad. Anyway I was just wondering what is the growth rate on these guys I know that they are slow growers but i was just wondering how much do they grow a month. Oh and he is in a 55 with a channel catfish and he is accepting hikari sinking carnivore pellets.
