Hi guys! Would like some input. Going from the 90 which has 2 severums, 1 angel and 5 Bolivian rams. I would like to add for the 125, another severum, chocolate, blue acara and re home the angel if need be. So it would be 3 severums, 1 chocolate, 1 blue acara, possibly keep the angel and 5 rams, could I bump their numbers up? Also, any room for a school of tetras? Thanks!!!!
