Hello! I've done all of my research on making sure the water conditions will be perfect for the fish. I have a 10 gallon tank with several real plants. I also have driftwood and a couple of small rocks. I have 5 neon tetras, 2 albino corys, 1 panda cory, 2 guppy males, 2 platy males, 1 swordtail male, 1 dwarf gouramI male, 1 ghost shrimp, 1 otocinclus , and 1 peaceful betta male. Keep in mind that I'm a beginner but I do know about the nitrogen cycle in case you were wondering. All advice is appreciated, thank you. The ammonia is 0. The tank has a aqueaon filter for ten gallon. I also have a heater and I do 25% water changes every two weeks. please tell me if I have a problem or not. My fish are all swimming well and no disease. I will not add anymore fish. It is a ten gallon long. I also replace the filter cartridge monthly.
