Hi! I have a 50 gallon tank, I had the water checked yesterday they said it was perfect. I have 6 neons, 2 honey gouramis, 2 platys, 2 tetras and just bought 2 angel fish today. The problem is with my neon tetras, they were perfectly fine before I fed them and now 2 of them(3 originally but 1 has stopped) look really bloated and are swimming face down and acting like they are being pulled to the surface. The are still active and all still have their color excpet 1 that looks like he is losing a teeny bit in his tail but not enough yt to worry me. They are kind of twitching too. I'm just really confused because they were fine before i fed them. What could have happened?, can they eat too much and bloat or swallow too much air to make them want to float. Please help I'm more worried about the rest of the fish in my tank. If it is neon disease how can I tell before it gets too out of hand? Although I really belive the feeding is what the problem is I just dont know how. I also added stresscoat to my tank today because of the angel fish. Thank you!!!!!
