Black-eyed guppy fry?
I just noticed a two week old guppy fry that does not have any "white" around it's eyes. Is this a mutation/defect, a disease, or a result of very high lighting on the tank? It is both eyes and while it makes the eyes look bigger, I don't think they are actually larger than any of the other tankmates eyes. Don't now if any of the environment info below is relevant, figured I'd put it in just in case!
1. Size of tank? 55 gallon, set up two months
2. Water parameters
a. Ammonia? zero
b. Nitrite? zero
c. Nitrate? zero
d. pH, KH and GH? pH 6.8, don't have test kits for KH and GH
e. Test kit? Mardel "dip stick"
3. Temperature? 24.5 C
4. FW (fresh water) or BW (brackish)? Freshwater

I would not worry about it. It happens normally with guppies from time to time.
I'm not usually convinced by dip stick tests though.:?
