no. i dont have any snails. the spot is on its side above its stomach its about the same size as its eyeball
it tells me the photo is too large

 

[WILDER]

OK. Justed need to make sure there was no snails in the tank as they can cause black spots on fish.
Can we take a look at your water stats please. Ammonia, nitrite, nitrate, and ph.

Black Patches

 

 

Symptoms:

Black patches, smudges, smears, spots or markings that suddenly appear and are not natural colorings.
 


 

Cause: 

These markings are the result of skin cell damage. Black markings often appear in areas where the skin has been damaged by ammonia burns, bacterial infections, parasitic infestations, and injuries. These markings are often seen on fish just after a new tank has completed �cycling,� due to the high ammonia levels. These marks are also common in African Cichlids, especially around the mouth. These are scabs that have come from digging in the gravel or from fighting.
 


 

Treatment: 

No treatment is necessary. Much like scabs, the blackened areas are a sign that the healing process has already begun. Keep water in top condition and the areas will gradually fade in less than a couple of weeks

You could try uploading the picture on photobucket and post it from there via URL.

Just keep a close eye on it for now.
Is the fish male, or female. As sometimes when females are pregnant you can sometimes see the fry eyes.
