grape Posted May 15 Share Posted May 15 Hello, I am an inexperienced fishkeeper but have been doing well for the past 6 months largely in part to the resources provided by Aquarium CoOp. I have longfin serpae tetras in a community tank and I saw some white splotches on two of them, as well as a bit of fin rot. I'm assuming this happened due to fin nipping as they can be quite aggressive. They are larger splotches, not dots like ich, so I thought it could be columnaris or some kind of fungus. I've never treated sick fish before, so I got a sterilite bin from Walmart and rinsed it out, put a heater and a cycled sponge filter from my main tank in it, and filled it up with water with the same parameters as my main tank. I then dosed it with IchX and Maracyn according to Aquarium CoOp directions. My fish appeared healthy in my main tank besides the splotches and their fins, but after I moved them to the hospital tank described above they died within an hour. This seems like a very quick time for them to go from swimming happily to completely dead, so I am quite confused and want to know what went wrong. Any thoughts? Thanks!
