I laid on my couch 2 nights ago and watched my yellow watchman jump into the overflow. Somehow it didn't get sucked into the sump, but it was a pain in the butt to fish out (ha). I also thought I'd lost a clown once and later found him in my sump, swimming happily. I've never seen him jump, but he must have to get down there! I'd like a solution to some kind of cover on my overflow! I'm scared that if I just cover it up they'll just have a flat, dry surface to land on. At least now they're staying in the water. I have a canopy, so they really can't get too far... just into the overflow.
I've had 3 jumpers total, but it's been over almost a 2 year span... and only one of them died.
