Ive had my afrowana for about a year and a half. It grew from 2" to a foot in the first year in my 75. I moved him into my 180 in august of 2013. Since then he has only grown to 15". He eats a pound of bloodworms a week, fed every day. He also eats(or tries to eat) massivore, tilapia, and krill when I feed my other fish 5 times a week. I do weekly 50-75% water changes. Lights are on in the tank only a few days a week. Tank is in the basement so there is not a lot of traffic to stress him either.
Why isnt he growing anymore? I was expecting him to be at least 18" by this point. Ive done everything I can and I fear that he is stunted. Tank mates are 15 polypterus, leopard ctenopoma, kingslaye ctenopoma, and a schilbe intermedius cat. He is definitely king of the tank, no tank mates bother him. If they do, they are in for a beating.
Temp: 78
Ph:7.4
