I have been keeping a smaller (~4"
female slider for the past year and a half in our outdoor pond (about 500gal) without and problems. This past week we purchased a slightly larger male to offer some companionship and put him in the same pond. Within a day or two, both had gone missing. We found the male about 30-40ft away hiding under a log, but he promptly ran away again.
What is it that I am missing here? Any suggestions for recovering our turtles and preventing this from reoccuring is appreciated.
