Hello, I have two baby red eared sliders. I got them about a week ago and they've been fine until now. I realized I did have "kind-of" dirty water.. So immediately I changed their water and cleaned all their objects in the tank. I have everything you're suppose to have to take care of a slider. They've been having puffy eyes, gasping, and hiccup like movements. Their eyes are like glued closed, I bought some turtle eye drops and they do help, but for a short period.I washed them both just in case it was something on them but then I realized they have some weird brownish skin in some places, like their hands. Also, they have been sleeping and basking a lot, for about three days. After looking at what the internet had to say, I believe that it's a respiratory infection, or something along those lines. Also, I don't know if I should turn my heat lamp off tonight or not because they felt kind of cold when I turned it off. The water temp is at 80 degrees.
Before you ask.. The tank is 10 gallons, don't lecture me on how it should be more.. I have a heat lamp, UVB lamp, water heater, dechlorinator, a basking spot, filter, vitamins, calcium, etc.
They're both sick, so should I separate them or just leave them in there together? I also have 3 mollies in that tank, are they okay in there as well? I'm thinking about going to the vet soon, how much do you think that would cost including the medication?
