+1 I grew my red out from 3 inch to 5 inch in a 30 ga now he's in the 70 up around 8 inch in the span of 6 months to give you an idea about growth rate (from 3 to 8 inch in 6 months), your tanks dimens are similar to my 30s just make sure you clean up wolves are messy! And mean, be careful w/ your fingers and tank mates.

If I keep one I will only have 1 wolf in the tank by himself. Any other suggestions for keeping an Erythrinus Sp.?
