I have found a home for all of my baby NW (Thank you Joe), except for the one male we are keeping (Fish Bait). My question is would it be ok to house him in the 20L with the rest of the adults now. He is about 9in long and a very good eater. I would take him out to feed, but other than that, is it safe to house a 2mo old in with the adults. The adults have shown now aggression toward him when put together for observation. Thought?
