Howdy. I recently ended up getting 2 puffers (T. fluviatilis variety) about 2" in size each. Unfortunately I only had 1 free 5gal tank at the moment. While at a minimum that would be ok for one of them for now, its not enough for both. I happen to have a 77gal Brackish tank with 3 Colombians, 5 Knight Gobies, and 2 Archer fish. What do you think a puffers chance would be in such a tank? If I move one into that tank do you think he'll survive. The colombians are about 7 inches, but are non-aggressive to the extreme (don't ask me how that happened) I'm more worried about the gang of Knight Gobies picking on him, or of the Archers taking picking on him. I have 2 planted tanks overflowing with snails, so live foods in that manner won't be a problem. Any thoughts?
