Hi, I've had my planted tank up and running for about 4 months and didnt put fish into it until about 2 months ago. My molly, platies, and betta are all laying on the bottom of the tank but still eating just fine and swimming around occasionally. I tested the levels and same as always. Ammonia=0.25 Nitrite=0 Nitrate=0. I don't know if this is what is causing them to do this or why I cant get my ammonia down. Also for nitrates if I'm not producing any if the cycle just didnt work or if my plants are sucking them up. I need help. Let me know if you need more info.
