Thank you. I’ll try the salt today. Now I have a quarantine tank as I unfortunately learned the hard way. I currently have some green neon tetras there for the last three weeks. I guess they will remain there until I am sure my Cory’s are healthy.

I’m pretty new to the hobby. I have two tanks. One with guppies in a 10 gallon and another that’s new that’s a 20 gallon long. They are both planted. I purchased 4 salt and pepper corydoras on 6/18. I added them to my guppy 10 gallon tank. I seemed to me the guppies were too active for the corydoras especially when it came time to feed them. One corydora died and another one looked unwell as well within about two weeks. I was prepping my 20 gallon long for them so I moved the remaining three to the new tank. They are the only inhabitants with the exception of pond snails. The cory that looked unwell died within a few days. The remaining two corydoras have been in the 20 gallon since. I just noticed one of them not as active recently and their dorsal fin seems to be down and smaller. Barbels are mostly gone on both fish as well. I just started treatment of maracyn yesterday. I just love my little fish. Any help is appreciated! Water Parameters: pH 6.8 Nitrates 10 Hardness 300 Nitrite 0 Ammonia 0 KH/Buffer 60 Water Temperature 75
