I set up my tank about 4/5 nonths ago. It had cycled and theb I put fish in it. 3 endlers, 2 black mollys, 3 guppies, two platys, 2 neons and a pleco. I have a 29G jbj hqI tank with a sponge filter abd heater. I have a few plabts and feed them once a day. I do water changes once ever two weeks of about 30%. I tested my water on the 17th and ammonia is 0.25 nitrite is 0 nitrate is 10 and ph is 7.6. my fish ever since I put them in tge tank are slowly dieing off one by one. Every couple days too degine with then its gone to once a week. In the end I lost 2 ebdlers, 1 black molly, 1 guppy, and a pleco. I don't understand why they keep dieing off I feel like I'm doong everything I can but I'm starting to feel like I shoukd just stop keeping fish cos its not fare on them keeping dieing. Oh ny temp is at 26c. Help me please I dint wabt then to carry on dieing and they show no sign of illness either.
