Yesterday I lost the yellow female, and there were no visible signs of illness. I've noticed illness in a few of the others, and am treating the tank with Maracyn Two.
My other male cobra had a little fin fraying when I came home today. Very slight. I didn't know if it was a nip, or rot, so I watched him.
An hour later, there was a severe rip, almost the length of the tail, and severe degrading. I put him in a sick tank, too.
I'm just confounded here... this happened in a tank that was being medicated for the last four days (fish were showing signs of dropsy, and dying) and Maracyn Two says it treats tail rot, as well!!
Is tail rot normally this quick and hard to cure?
I've read a lot of people here say they cured it...
I've used Maracyn Two, Melafix and Pimafix, and one of the green anti fungal/anti bacterials for tail rot, on different fish, and they all completely lost their tails and died within a few days.
I also lost a five month old fry in another tank for no visible reason, a few days ago.
I'm very discouraged at this point, and I think we've decided to hang it up for now, once the illness runs its course in this new tank.
I just can't find healthy fish anywhere! I'm beginning to think maybe it's something I'm doing wrong? I cannot afford to order expensive fish online, and I'm not sure I want to if it's something I'm not doing right. Quarantine doesn't seem to work that well for me, either, as I've now had fish that don't show illness for 2-3 weeks! My heater went out in my main sick tank, and I'm left with only a 2 gal tank with no heat and an airstone only. Not sure I want to put the expense into fixing a tank at this point.
