My African Clawed Frog was swimming around the other day & bumped his eye off a rock i have in his aquarium. It started bleeding right away but stopped within seconds. Then i noticed under what i guess is a eyelid, his eye turned black with some blood in it. Hes still swimming around like nothing ever happened. I understand ACF are excellent healers. & can heal themselves. However, will this go back to normal completely? I'd hate to see my frog half blind!
