Hello all! Not new to the hobby but I never feel like the sub-forums get much traffic compared to the beginner page. Anywho, I have a very sick bumblebee cat! I've never seen this before in all my years of fishkeeping and need help diagnosing this thing. I'm not too concerned about saving the cat but I need to know if whatever this thing is will spread. Everyone else is happy as can be, so there are no other symptoms showing in everyone else. I noticed this morning before class that this cat had come out and was gasping VERY hard. It struck me as strange because I never see him out day or night. He's been living hidden away for maybe 6 months. I started with 3 and the first died around 3 months ago, no symptoms that I could see (mostly because he was skeletonized when I found him. I believe there's another hidden away somewhere because I haven't found any skeletons but I have no idea because they do nothing but hide! Anyway, ammonia is fine at around .15-.25ppm, no nitrite, and nitrate is around 10-15ppm. I don't know how well my pictures will turn out so I'll describe his symptoms as best I can: he's covered in deep lesions and raised cysts. Definitely not ich and it doesn't look bacterial. His fins are spotless and unaffected as far as I can see, it's all on his body. Like I said he's gasping very hard and his eyes are milky. His abdomen looks swollen, maybe abdominal edema caused by internal infection but I know bumblebees are a little pot-bellied naturally. Any help is good, thank you!
