So ill start by saying i added a new fish to my tank and he was the first to go, it was a blue johanni. that same day my red jewel started changing colors in what seemed to be underneath his skin. it might have been bruising from all the substrate ramming he began doing. i also woke up this morning to a dead convict, he like the red jewel had a large blue mass on his stomach which had not been there the night before. my biggest fear now resides in my angelica catfish who has a weird fuzz in certain spots on his body. the fuzz is making me think its not ich but something else. i have good filtration and have been changing my water weekly. Any pointers would help thanks.
