I have had a 20 gallon tank for a year now. Since I got it, nothing has stayed alive for more than a few months. I do water changes and I try to make sure everything is good in the tank. No matter what I do, most of the fish i put in there die. Recently, I have 1 male swordtail that i have had for a while, 1 loach for a while, and one female swordtail that i have had for a little over a week. At first, I added her and everything seemed fine. Now, she hides in a corner with her fins clamped. The male was acting fine until a day ago when he started acting similarly. Other than having to do a water change, what should I do to ever have a stable tank? Nothing I have ever done seems to help and it is making very fustrated.

Ok Yesterday I did a 50 percent water change and add some chemical to help reduce the levels but it is not working. what should I do. I have a freshwater tank. I have to dwarf gourami, 2 short skirt tetras, 3 guppies, 1 black molly, 2 red cardinal tetras, 1 flame tetra and 3 neon tetras. Please help dont know what else to do.
I have bought stress coat and cycle, also I am using AMQuel plus to help with nitrate and nirite

developed ‘ich’ and to prevent this from ‘exploding’ in the tank to everyone else..I treated the tank with malachite green and formalin-raised the temp to 84 degrees..during the treatment another of the clown loaches got ich..and I had to do partial water changes after 3 day..as the first one still had it…and redo the whole treatment a second time..I have since done a substantial water change and am using charcoal to try and get the tank back to it[’s good condition. I have gradually drop the temp to 78 deg Everything is going fine.except the loach that was originally ill. He was never as strong as the rest( probably why he got ill in the first place.). He tries to interact with the other loaches and does so intermittently..but spends much time on his own sleeping beside the heater…He has a good appetite-have been feeding him flake food, freeze dried shrimp, and freeze/d blood worms…but he is still very thin..Can I do anything else to get him to gain weight and be more healthy?
sorry –feeding him frozen shrimp and bloodworms…not freeze dried.

How often would i do a water change for a 2litre fish tank?
