found one for sale in the local shop for 40 bucks--anyone had experience with one of these? i've kept my leo on a diet of exclusively superworms for a long time now. (he wont eat crix, very picky guy). ocassionally he goes for a week without eating, i think possibly out of boredom. however there are times when he will "zero in" on a worm, get up close enough to strike, and then lose interest. i think this may be a vision thing due to the worm not moving around enough and i thought the dish would help. anyway if anyone's had experience let me know, if it works it may be a worthy investment.
