Hi there. I've been following this site for the past month and a half now since I've started up my first freshwater tank and have gotten a lot of great info from you guys. So I have a 15 gallon with 5 glofish tetras (the ones genetically modified from white skirt tetras). I know this was probably too many fish to start with but my daughter was very excited about them and I caved. So I did water changes at least every other day to keep the ammonia below 2ppm. Unfortunately I didn't discover Prime until 3 weeks into the cycle, so the fish were pretty much getting the full brunt of the ammonia. Well luckily less than a week later the ammonia was gone, had the nitrite spike for 2 days, then *boom* it was cycled. For the past 2 weeks ammonia and nitrite have been at 0 and I've kept the nitrates below about 20-30ppm. Luckily all the fish lived, but they've still been acting quite lethargic. Maybe this is normal behavior, but they all just kind of hang out in their spots not swimming around that much until feeding time (which they still go crazy for). I'm just wondering if the behavior is due to permanent ammonia poisoning or if they will snap out of it eventually or if this is just normal behavior. I'm wondering if just adding a couple more fish will liven them up. Any insight would be appreciated. Thanks!
