Initial post here with pics:
basic run down: have a 75 gallon freshwater tank with Cories, Pleco, Australian Rainbowfish, Bosemani Rainbowfish and Red Eye Tetras
Ph between 7.6-7.8
I lost 3 cories recently. They had fin rot so I upped the cleanings.
After cleaning I added extra de chlorinator (Prime). There have been no more cories deaths and all fin rot seems to have stopped.
Yesterday I noticed one of my females has some white spots (not ICH, not fuzzy) on her head and both eyes are a bit cloudy. I have had her for 2-3 yrs.
Did a run with Kanaplex with no results.
Noticed a cory also had whitish skin (I wouldn't say it was fuzz) on his back and did a round of Kanaplex and Furan 2.
I have wanted to up the salt but have a Pleco and Cories so I was hesitant. I think I should have heard plecos are ok with salt and that they need less salt. Need exact measurements.
I would dare say my fishes scales and fins are rotting away. Can't say for sure. This has been going on for a month so I wouldn't think it was Colomnaris.
I have had:
a dead cory that looks like he had some red spots.
a dead cory that looked like he wasted away
I have now:
a female rainbow fish with white on her head and eyes, fin rot, dropsy and she is pine coned.
a cory with either fuzz or dissolving scales and popeye
2 cories with popeye
a few other rainbows and tetras with fin rot.
some have a little black spot here and there but NOT a lot at all so I don't think that is anything. Any ideas? This tank has been stable for years so I am really bummed about this.
There is a chance that it is Fish Tuberculosis I hope it isn't and am reading up on it more. If it is I have been battling this for a few years and it was introduced to this tank by cross contamination.
If there is any advice anyone can give me I'll take it.
