I have a 55 gallon tank, upgraded from a 20 gallon 4 weeks ago. 7 white skirt tetras, 4 albino corys, 1 pleco, 1 guppy moved over from the 20 gallon. The old bio filter media went into the new filter, a cascade 300. The old gravel, plants(anacharis, java/flame moss) and driftwood moved over too. After the new tank had been running for 2 weeks and parameters were normal I added a 3" angelfish. The following week I added 9 rummynose tetra.
The day they were added, I noticed that one of the rummies was hanging out at the bottom of the tank and not schooling with the others. It eventually twitched, turned over and died by the end of the day. The following day another rummy died in the same pattern and two more that day after that. The remaining 5 rummys have been stable and normal for the past 4 days. Yesterday morning I found one of the corys dead. This morning 2 more were dead. None of the corys showed any indication of a problem before hand.
Can anyone point me in the direction of what might be wrong? At first I thought that maybe the rummies didn't acclimate well or were a just a bad batch but then the corys died. I was then thinking I might not have given the new tank long enough to cycle but the parameters were normal before and after the deaths.
pH 8.0, KH 120, ammonia 0ppm, nitrite 0ppm, nitrate 10ppm, 76-78F. I've been doing 30% weekly water changes. I alternate flakes, pellets. Bloodworms once a week, fast once a week. Algae wafers once or twice a week.
