OH GOSH.... What do u mean by one eye is missing and healing over? All I see from your pics is that both eyes are cloudy which is not a norm. Try to keep your water quality high and add Melafix to see if they recover after a week or so. Trust me I have worked with at least 6 specimens to date and this species down with cloudy eyes may or may not recover unlike others... But you really have to try to hurry treatment asap as the time frame is really critical. As for the fins as long as the hard or rather first rays and adipose fins are not affected then will heal in no time as they are the catfish version of Hoplias aimara (X-men Wolverine) And it is always a great thing to have a very bad tempered C.apurensis rather than a mild tempered one lol. Mine is pushing 7" to date and I'm goin to start puttin in similar sized common plecs and marbled gobies to let it wack lol... Teddy bear monster catfish in d makin hahaha....
