Can I suggest a measured wait and see approach instead of giving up?
We went thru a lot of the same things together, with sterbais and rummies back in early March. From all those fish in my quarantine tank of death, all that survived are 3 rummies. They won the lottery, if u want to look at it that way. They remain healthy, now they’re in a rather understocked tank that looks nothing like what I envisioned or dreamed when I was setting the tank up. I fought hard against this outcome, but now that it’s what I have... I LOVE IT!! Less maintenance, no dying fish, no endless trips to lfs for more or new meds.
Look for the silver linings, my friend.
I never properly responded to you, my friend. I actually don't mind if we end up not having sterbaI or any Cory cats in this tank and maybe add a few golden barbs instead or leave it under stocked.
I'm most gutted that we can't order a replacement EBJD until we figure this out. and I don't want it to spread to the other species in the tank... which seem slightly low on appetite but otherwise sweet as.
thank you for trying to help. I can't believe how often I've needed fabulous people like you since getting myself schooled on this hobby. .. it's depressing ..but I'm really grateful to you.
