My 125 that started with 4 goldfish I converted into a tank for 2 oscars, and silver dollars. nothing wrong with that, but I am not happy with it basically....so I will rehome the oscar inhabitants to a good place. Anyway, I been wanting discus for YEARS ever since I joined this forum actually. It will take a bit, but it's fine my 125 is going nowhere. I can rehome the current stock, Rescape the tank. Then the fun part. Anyway, I'm in short asking how would YOU properly stock a 125 built around discus. I would like lots of cardinals, I'd like to stock a lot of them first, then add the discus and hope they don't become snacks later.
