The vatf will be in an 50 gallon grow out so there is no need to worry about the rays he will be a good size when i transfer him
You say one is already 8-9 inches, you're getting a small atf. I doubt he'll keep up in growth. DB said it best, pick a species, a smaller one, and build the tank around its needs and add tankmates wisely that you know it will be fine with. And sorry if I came across rude but yes you were confusing me, out of those options you have do the one vatf. 3 would not be fine and an army will get to large if you manage to keep it passed 2feet which seems hard from others experience. Rays will get to large. I like to plan for what I have and not what I might be able to get. Because there's always a possibility something will happen and you won't be able to go any bigger.The vatf will be in an 50 gallon grow out so there is no need to worry about the rays he will be a good size when i transfer him
