1. The patient is a keyhole cichlid, approximately 3 years old, 1/2 of a breeding pair.
2. Symptoms: Lethargy, hiding in back of the tank near the top, not swimming around much like its mate. Facing backward in tank. Usually a VERY aggressive fish as far as food, territory, etc. No outward signs of parasites, fungus, etc. Not interested in food.
3 ammonia=0 nitrites=? nitrates@15 temp 84 pH 6.3
4. 90 gallons, set up around 3 years, heavily planted, CO2
5. Tankmates= 4 discus, 2 dwarf pleco, 15 cardinal tetra, 3 flagfish and its mate, the female keyhole. All showing no signs of problems
6. I use the estimative index for dosing ferts so I change 50% of water once a week. I have a Fluval 404 plus a similar sized eheim professional II running on the tank.
7. The only change I have recently made is to feed the entire tank some live redworms as a treat. The male keyhole, as he is usually a pig when food comes around got more than his share.
I just set up my quarantine tank and would like to know what you guys and gals would suggest as to my first course of action.
