A few months back, I got a group of female bettas, and three males. The males are all in different tanks, of course, and the females numbered six in a very well-cycled, well-planted tank. Constant checks showed all to be well, and all my fish were living in total harmony.
Until maybe two weeks ago.
First, our favorite female, Katniss, died. No cause was apparent. Checking the levels of ammonia, nitrates, nitrites, all that kit stuff showed no apparent reason. Our favorite female, a beautiful green delta, had died for no reason and I could do nothing about it.
Next was almost all the females in rapid succession - only two remain, as healthy as ever! The levels are still perfect, not a single thing awry, and the corydoras catfish show no illness whatsoever. However, a few placostimi have died as well. One female showed mild signs of what may've been pop-eye, but it was only barely noticeable and we hadn't even gotten the chance to give her a treatment before we lost her.
Next was a gorgeous, gorgeous black orchid crowntail male, with no causes apparent other than weeks of lathargy - Severus had been healthy enough except for that and refusing to spawn(We'd gotten him to with our dear Katniss once).
Now our dragonscale Tobuscus is near the edge of death. He appears to have ich, but I have never
heard of it killing a fish, and we've given him a salt bath every day for at least three days now, and it just won't go away. He lays at the bottom of the tank, on his side, and can't even get all the way up for air in a half-full tank which we planned to spawn him in. We now have him in a shallower cup full of medicine in hopes that it could help him. Toby is the only one who has any outward signs of disease, and that is small, white specks all over him. We simply cannot figure out what on earth has killed five fish in a week.
The only thing is a high ph of 7, but it's fairly stable. Other than that, everything is all fine.
Please help us.
