I have 11 panda corys, 6 peacock gudgeons, and 3 tetras in a 20 gallon long tank. I made the mistake of not checking on here before buying the fish, and now I'm stuck with more fish than I have room for. The best solution I can think of is to get another tank and split the fish up between the two tanks because I don't know of anybody I can re-home the fish to. The problem is, I can't afford to buy everything to set up another tank right now, and I don't have any additional cycled filter media, so even if I could buy another tank + the supplies, it would be weeks before I could put fish in it. So my question is, if I keep up on my water changes, and keep my water parameters at a good level, will the 20 gallon tank be sufficient to house them temporarily? If not, I would love any ideas you have to offer, and thanks so much in advance!
