Hi all,
I have a bit of a problem. About a month ago now, I bought a new Turtle Topper for my 55 gal. tank. I have two young sliders (YBS) and they're shy baskers. The reason I went with a topper is A) because they were getting too big to both comfortably bask on the floating dock without partially capsizing it and B) having a low water level makes the SUNSUN filter really loud.
It's that ubiquitous commercial Penn Plax Topper.
Now, they can both get up onto the dock, so physically it isn't a problem - but I don't see them bask -ever-. Pinkman, the smaller of the two doesn't even choose to go up there at all unless I coax him with treats. Mordin, the larger turtle, climbs up periodically because he knows I leave treats there sometimes, but he won't stay in there and bask.
It has now been weeks since I've seen them spend any time basking. I keep checking their shells for abnormalities, but I don't see any. I'm still worried though.
What do I do?
