8. Are you using a CO2 unit?
9. Does your aquarium receive natural sunlight at any given part of the day?
None at all
10. When did you perform your last water exchange, and how much water was changed?
Six days ago, the fish were moved to a new home so only about 30% of the old tank water was retained, making it about a 70% change
11. How often do you perform water changes?
Normally, about 25-30% weekly
12. How often and what foods do you feed your fish?
Twice daily, flakes, shrimp pellets, algae wafers, live blackworms, frozen bloodworms, tubifex and brine shrimp. Occasional veggies

17. When was the last time you bought a fish and how did they behave while in the pet store tank?
Last fish added were the kribensis, added late December. They were typical skittish juvenile kribensis.
From what I've read, pop-eye in a single eye on a single fish is a good sign of an injury. The fish are due for a water change tomorrow - should I go heavier than I normally would and step up the water changes? From what I've read, it's likely that it was an injury that's now infected and antibiotics are par for the course. I don't have another tank I feel comfortable putting her in at the moment except possibly the 5g guppy tank, but I don't know if I should separate her from her fry in order to medicate. What should I do? I don't want to risk destroying my biological filter by using antibiotics in the tank she's currently in, and I'm not sure I should medicate with the fry as young as they are.
