Hello, my wife and I have been in the hobby for less than a year. Once we got through the terror of learning about the nitrogen cycle with live fish we thought things were clear and dandy. Then one day in December we lost a guppy pretty randomly didn’t think anything of it. A few months goes by and we lost a platy, then one of our glo fish danios very quickly faded away to nothing, at which point I thought for sure the glo fish had a parasite. To be certain we treated all of our tanks with general cure per the instructions for a week. I also made anti parasite food with metroplex and focus. Thought that should nip everything in the bud but now we have a sick guppy with dropsy, scales are pineconing imagine it doesn’t have much time. Throughout this whole process ph is stable at 7.2 no ammonia or nitrite spikes and I change the water as soon as the test creeps towards 40 nitrate.
The sick guppy is currently isolated with epsom salt and melafix. Am I missing anything? Have I done something wrong, I don’t want to keep killing fish but it seems that I keep getting them sick despite keeping up parameters. Thanks.
