My eldest set up his own 20gal tank a few months ago. Now that he has a part time job, a new tank was high on his priority list. He stocked it with 6 Neon Tetras & 4 male Guppies. Unfortunately he is having trouble keeping the fancy guppies he likes alive for more than a few weeks. They are fine for the first few weeks & then one by one they end up sitting on the substrate & not coming up for food. A day or two later they will die. There are no visible injuries or parasites & there is no rapid breathing. He replaces the ones that die on him.
If this was anyone else I would say that it is a water quality issue, probably ammonia. However I assisted him with the fishless cycle & we test the water together right before he does his weekly water change. The results are always the same, Ammonia 0, Nitrite 0, Nitrate 10, PH 7.6 & temp is 77f. Tap water has the same parameters (without the nitrate) & he heats it to temp before water changes. On top of that, the 6 Neon Tetras that share the tank with the 4 Guppies are doing just fine.
Anyone got any ideas? I'm stumped.
