Is this Lymphocystis? On 1 of 8 fish. If so, do I have to worry about my other cpds getting it and is there any reason I shouldn’t breed these guys? Planning on moving them outdoors to a tub for the summer.

I’ve noticed that many of the Peacock Gudgeons that I have appear to have a prolapsed anus. Some have this present, others do not. A quick look at google images at Peacock Gudgeons reveals a similar result. Is this typical in Peacock Gudgeons? Is this something to be worried about? pH 7.8 GH 10 KH 7 Ammonia 0 Nitrite 0 Nitrate 20 Temp 80
