KRSwop1;648504; said:I think you have some of your info mixed up. Erythrinus Erythrinus is the rainbow wolffish/ high-fin wolf fish/ red high-fin wolf fish (all common names), and they reach about 8 inches or so. Hoplias malabaricus are known as common wolves, and you are correct, they can reach about 20". Hoplerythrinus unitaeniatus is another wolf that doesn't get extremely huge. They max out at around 14-16", but require a lot of swimming space because they are the most active of the wolves. They swim almost constantly. Good luck in your wold keeping.
So is the erythrinis available anywhere??
