About 3-4 weeks ago I got a convict cichlid for free from the pet store because it had popeye, and they weren't going to treat it. So I took it home and put it in a 10 gallon hospital tank. First I treated him with the medication "Maracyn" for a week, with no signs of improvement. So I've switch medication to Melafix and Pimafix. I treated him with this for a week. There was no sign of improvement. So I stopped treatment to see if it went away on its own. Its gotten a little bit better, but not alot. What I was wondering is if he could have cloud eye instead of popeye? Or if he has an internal disease, which is causing the popeye. (I would post a pic of him, but I can't seem to get my pictures to download)

Popeye or exophthalmia is a symptom, not a disease in itself and it can have a large number of potential causes. some of these causes are incurable while others can potentially be cured on a sporadic basis.

the bulging or protruding eye(s), as the name 'popeye' implies, is symptomatic of this condition. potential causes include --- infrequent water changes which results in a buildup of dissolved waste products in the water, Ichthyosporidium -- a parasitic fungus, Ichthyophonus, 'worm cataract disease'-- a function of the invasion of parasitic trematodes or flukes, bacterial infection, parasite infestation -- eye flukes and internal metabolic disorders.

since the causes of popeye are so varied, the treatment is difficult. some success has been noted in treatment of Ichthyosporidium using one percent phenoxyethanol at about 50gm per gallon of water.

treatment for bacterial disease would best be accomplished using Tetracycline or Teramycin added to aquarium water every other day or mixing food at the rate of 100 mg of antibiotic to 4 oz. of food. Feeding should continue 10 days.

Fish tuberculosis can also be responsible for pop-eye. Since fish tuberculosis is a bacterial disease caused by a Mycobacterium, the same antibiotics can be used in the same manner for treatment if this is the suspected cause. other effective treatments for bacterial exophthalia may include Chlortetracycline, Furazolidone, Nifurpirinol, Oxolinic acid, Oxytetracycline or potentiated sulphonamide. unfortunately these treatments are most effective when injected into the eye socket and less so when used as a bath.

if the fish has eye flukes, malachite green with formalin, metriphonate or copper are good, as are most of the commercial preps for flukes and external parasites.

this disease is rarely fatal and not particularly infectious. it often disappears on it's own in 2-3 weeks leaving no residual trace or may disappear leaving a cloudy eye and worst case, a missing eye.

i've rarely found that aquarists have 'cured' a case of 'popeye'. rather, some have gone from medication to medication and never found one that works. this is likely due to the fact that the cause was never differentiated.

i think i'd give it at least two more weeks and see what happens. stop the other medications and keep the water quality pristine. it may resolve itself.
you're never too old to have a happy childhood.
