thanks for you replies.tried increasing the water level:

if i put dumbork on the ramp, the ramp stays still (secured with a zip tie). but then, dumbork will become skittish and dive immediately into the water. i tried putting some pellets on the basking area.

(the small turtle there is a toy). hopefully when i come back from work later the pellets will be gone!

) how much time do turtles need before acclimating to new surroundings anyway?
hope i have one of those motion detector camera thingy so that i can monitor his movements. wish us luck!
