that's good to hear re feeding your diamonbacks! Makes the prospect a lot more viable. If you have a gopro type cam with underwater case, it would be interesting to see them under the water. Hint, hint!
I usually take a lot of turtle pics as they're pretty photogenic! I'll put some up probably June, maybe mid-May. Depends on the weather. Made them a new basking log (among the others that stay along the banks) out of cork as the old one finally got too water-logged (pun intended!).
My painteds DID like to eat the parrot's feather and varigated clover (and probably the hyacinth roots, but I can't tell as the underwater cam doesn't show that part of the pond) so I've had to create nets and such to keep that type of plant. Any overgrowth is open for snacking, though. The lilies occasionally get nipped (I think; it might be the koi) but I don't see them actively doing any damage.
Now, I deliberately started with small, 2-3" painteds hoping their size would stop them from doing much damage to either fish or plants. Hoping they'd 'grow up' with the fish and essentially leave them alone. Which so far is working. I put a large, adult male in there one time that I found wandering across the road and noticed nipped tails immediately, so he went to the big pond down the road. Diamondbacks don't get much larger than the painteds, if I remember right. Would you recommend getting more than one, if I end up going that route, or would one be just fine by itself? I tend to like to get pairs, at least, not that I'm really looking for baby turtles (that's for the painteds, in time, hopefully).
Thanks for all the turtle talk, jhn!
