What is wrong? ((Help)) I have been having a lot of problems lately! My female prego guppy has a stinky bloody tail and the bottom of her gills are dark red. She is not having any trouble swimming that I can see but is trying to stay in shallow water. I dont know what is wrong?? I dont see how the other fish could have harmed her because they are just tiny baby guppies. I had her feeding a mild helping of soft boiled inside of an egg mixed with water, I had read to feed that to fry off a book and I doubt that had anything to do with it. I just changed the water in the tank and put the rocks in a bag. The tank is bare and filtered and I put her in there with a tiny newborn baby. I moved all the young adults in with the full grown adults. Does anyone know what is wrong with my big girl?
