Well, the nails are NOT too long, so that's one problem solved. About the eyes...they are not swollen, just squinty and moist. I don't know what would be causing that. Do you keep them on sand? Sometimes sand irritates their eyes. It may help if you flush his eyes with sterile saline a couple times a day for a week or so. Soak him every day and keep him warm. Hopefully you'll see an improvement. Oh, and keep him separate for a while. Male russians just want to breed the females all the time, and taking that temptation away from him will help him settle down.
I cut the nails that were really long they were in the back. They could've been kept on sand before me, but I use coconut substrate. Im soaking daily an have separated them. The problem is, he is too settled down and lethargic.
