i hate wolf fishes. i tried 2 at different times and gave them about a 3 month settle in period and neither one would ever eat except night time and all they did was lay on the bottom like a rock. my dorado beat the bs out of the wolf fish and was glad to see it but i figure i could get a couple bucks out of em at the lfs and told them to stick it and never bother trying to sell me another one again.
