just found out 2 days ago that my delhzi has an eye injury on the right eye, there is blood covering the eyes and up to now it hasn't cleared up yet, i am worried that the blood might cause the right eye to be blind, not sure how the injury happened, might be from chasing feeders, removed the feeders already, the treatment i am doing is i placed tetracycline and rock salt in the tank, so far not much improvement, i can still see blood around the eyes
