Well Tyler... triggers really should have no less than 90 gallons but it also depends on what/how many fish you have with it. This specific trigger doesn't get along with anything- so he is in my 72 gal bow all by himself. Niger's are pretty good with other tankmates, and huma huma's are too although when I got this guy there was a smaller Huma Huma who was the boss of that tank. So it all depends on the fish. Im currently trying to build this guy's future home in my bedroom wall- we'll see what happens.
