So Ive gotten a good idea on what species of fish I wanna stock. As you can tell on the title its tetras, GBR, and Discus. My next question is if there is an order to placing these fish into the tank?Like should the Discus be in the tank first then the GBR then Tetras? Or do you just add them all together? If I wanted to add fish at different times, to save money what order could I place these 3 species of fish?
