Hi all sifus,
I have two red ear sliders that I raised at my home currently. Both of them i suspect is infected with shell rot but i'm not sure how to decide. Both of them are eating fine and very active. The condition has been showing for over a month now (for the older one, over 2 months). And I bought medicine to apply but so far no effect. Should i be concern? One of the younger one initially has very nice shell with no spots on the shell when I first bought it, after I bring it home and put in the same aquarium as the older turtle, it started to show the same symptoms as the old one. which is showing patches of grey on the shell.

Attach the photos of the turtle.

Older turtle (female). Got this during school's carnival sale.


Younger turtle (male). Initially when i first bought it the shell is really green with no grey spots around the edges or on the shell.


Medicine. I bring both out to a smaller dry aquarium to put on the medicine. After one or two hours, I put both back into water.



My setup:
1. Water filter (water change every week)
2. Basking area (for some reason, turtle don't like this)
3. UV light (on during the day)
4. Basking light. (not on most of the time)

Water temperature is around 31 degree everyday. Is the water too high? The turtles doesn't like to come to the basking area.


Any ideas?

Thank you.

Thanks tygoh. So there's no problem with it? My turtles doesn't like to bask. Is that Ok if they stay in water long time?
