I have a comet goldfish i pulled out of a piranha tank, He lives in a 2 gallon tank right now, with an air pump, and a couple small plants. I have a 20 gallon tank cleaned out, but i want to stain the stand a darker color before i set up it, plus buy some sand, plants, rocks, air pump and air stones, maybe some LEDs. My plan is to get a chocolate moor to live in the 20 gallon, with an emerald cory catfish if i can find one. I know the tank my fish is in now is way too small, and i know that my comet may bully the moor because they are slow and handicaped.
i also have a filter and a heater for the 20 gallon,
