My 200L tank has always been well maintained. EI ferts, CO2, and weekly 50% water changes. That is until about 4 months ago, I lost 50% of my fish due to overdosing CO2, and it has been subsequently neglected for 4 months due to family illness.
2 weeks ago I got the tank into good order. I chucked all the unhealthy and indeed healthy plants. Cleaned filters etc. Substrate is the original, JBL aquasoil Now replanted, plants going well. Added a dozen cardinals and a few very small angels. Water parameters are all good.
Only problem is I'm losing my original survivors,5 fish in the last 5 days and my last hatchet about to join them. Absolutely no indication of any fish Ill health, no fungus, feeding fine, and then dead. The hatchet is the exception and hasn't looked well for a couple of days, but no external indication of anything wrong.
I have treated today with an anti bacterial medication. Any ideas what may be the issue? New fish from very reputable suppliers.
