3. Symptoms / Problem description
Noticed this afternoon that one of my Albino's eyes is bloody and his retina looks detached. His other eye looks totally fine. I couldn't really get a shot of the other eye because of the angle and he's still in the 20 gallon (I don't want to move him unnecessarily). I just changed the water today. I put in 1 TBS aquarium salt per 5 gallons water. I added 10 gallons of water total today. Also added API Stress Coat + (10 ml for the 10 gallons added).
4. Action taken (if any)
None yet. I just discovered the problem this afternoon. I was going to put him in a hospital tank (3 gallon Tupperware container with 1 tsp aquarium salt per gallon). Not sure what to do with sand. Thinking it should be bare bottom and just give him a quarter of an algae tablet each day. I've never had any problems with this little guy and have had him since he was a baby in December. All the other cory's look fine. I just added my betta back in the tank today (he had a bump on his side and he has spent 2 weeks in quarantine. Thought it might have been constipation but the consensus from the fish community is that it's probably a tumor since it's near his anal fin area).
5. Medications used (if any)
None yet. Not sure what I should do. Any help would be appreciated.
