How many gallons is the tank? I read that a cause of drop eye is pond breeding and inbreeding. Black aros do not have this problem because they are wild collected. Did you raise your fish from a baby like the one I just got? How much meat does your fish eat everyday?
Yeah he's got drop eye on one side. Really don't know how to get it fixed. Gonna try ping pong balls and cover 3 sides of the tank and see if it works. Could be genetics. I don't care really. Still love him.
sorry to say but covering up the sides and ping pong balls wont help u there but its in the arowanas genes and these silvers have been kept pets for a long time now so yea... mines even has it but i like though i like how the top of the eye is green and red multicolored it actually looks nice on mines i like it but some ppl dont thats their preference....
