Hi Everyone! We just started up a 10 gal aquarium, and regretfully didn’t know about cycling the tank first, and sadly we lost 3 of 6 male guppies. It’s been about two weeks and the remaining fish are lively and healthy, and the water levels are good. However I noticed some fraying on one guppy’s tail and a pattern of the largest guppy chasing him and nipping at his tail. After reading a lot of different information, I’d really like some advice on what is the safest and best route to take to help the guppy’s tail recover and prevent injury among our fish: Should I move the injured fish to a separate tank with Melafix? Or would being moved be stressful and do more harm than good? Should I add Melafix and or aquarium salt to the main tank, or will that disrupt the good bacteria that seems to be finally established? And will the bully fish hopefully get better if we add more guppies, or is he likely to attack everyone? Pic attached, the dark blue guy is the one with the wounded tail, but it’s a bit hard to see, they rarely are still enough to get a good pic. Really appreciate any insight, thanks!
