Thus is the problem with this hobby. Ten years ago I started with a 20h tank and a handful of danios. Now I have a 75g fully planted with a pressurized co2 delivery system that I'm dosing ferts all the time, a 55g cave biome, a 29g SW tank that I am not entirely sure what I'm doing with and 3-4 tanks of various shapes and sizes that are completely empty. Worse than this when I walk into my spare room and see my empty tanks, my thought is, "I need to buy a bigger house so I can set up all these tanks."
