Finally got a nice piece of cork oak bark and anchored one side of it with jungle vines so Fifi has a basking platform that doesn't limit her (still insufficient, but better than before) swimming area. Allowed me to raise the water level a bit, too. It floats pretty well under her weight, but doesn't stay 100% above the waterline as I have it now. So her shell is getting good and dry when she basks but her plastron remains in some amount of water. Is that OK, or do I need to add supports or a second platform that I can get to sit completely above the waterline?
Also, some little bits are breaking off the bark when she gets on/off it. I've been skimming them as I notice it, but will it hurt her if she eats them?
And on the topic of cork oak, where do y'all get the large pieces that you can cut to fit the tank?
