I've had her for a year now, and up until about a month ago she was always fanatical about feeding time. Damn near took my fingertips off when I gave her the pellets. But lately she just doesn't want them, or anything else. I've tried bloodworms, mysis shrimp, lettuce, peeled peas, zucchini, a combination of those mashed in with garlic juice, spirulina flakes, even honeydew melon. No dice. Her feces (what there is of it) is healthy looking, not white or stringy. Her stomach looks a little sunken, but above that her heft looks normal and her scales all appear to be healthy. No anal redness or protruding worms. Eyes clear, no injuries, fins undamaged. She acts normal, no swimming in circles or gasping at the surface. Water parameters (taken this morning) are NH3-0 NO2-0 NO3-10, and she's by herself in a 50gal. Temp. 77. Her color is a little pale, but she wasn't exactly colorful to start with. Since I've gotten her I've faithfully performed weekly water changes of between 60-70% Two filters running, an AC 70 and a Rena XP2. Does anyone on here have any experience with this sort of situation? She's about 11", and I figured a fish that size would be more than happy to chomp on a meal when given half a chance. Any tips on what my next move should be would be greatly appreciated. Maybe I've got a piscine supermodel, but I don't want her to starve herself to death...
