I have 2 questions bout my RES:
1. is it ok to have sand on the tank bottom? in a book I have on keeping turtles it says that it's ok, but I have heard that turtles eat it and can get sick and even die. Should I take it out?
2. I've been feeding him mostly pelletes & gammarus. I plan to improve on this. I've noticed that his shell is a little bumpy compared to some pictures I've seen, nothing monstrous but still... Could it be due to poor diet and will it improve when I start to feed him better?
Thank you
