Alright, would these fish be able to survive in a 20 gal tall? Just wondering about water problems possibly, not if they coexist well. Arulius Barb, Rosey Barb, Buenos Ares Tetra, Skunk Loach, Bleeding Heart Tetra, Scissor Tail Rasbora, Mickey Mouse Platy, and a Cory. 8 fish in one 20 gal high okay? Especially with proper filtration, plants, hiding places, and frequent water changes?
