Okay I have a 20 gallon tank with 3 mollies, 2 danios and 1 cory. One of the mollies was dead this morning when I woke up and the other fish were alternating between the bottom of the tank and the surface. Not enough air Im thinking. But I thought that air thingys were unnecessary for fish tanks. Anyways what would be the best way to remedy this. By the way I started this tank 3 weeks ago and knew nothing of cycling till now. I have been doing water changes of about 20-30% every other day and the ammonia stays at 1.0 ppm. Will it stay like this forever or will the ammonia eventually disappear??? Thanks.
