Butterfly,
Thanks for the thread! It was great. Love the idea about sliding the zucchinni/cucumber down the side of the tank. I will have to try that tomorrow. I tried lettuce today in addition to their regular zuchinni - They do not seem the least bit interested in the lettuce (romaine)...fine with me

Maybe peas after a trip to the grocery.
I didn't spot that anyone answered the tomato question - I was reading quickly and may have missed it. My thought is that if acidic is to be avoided, it seems that tomatoes should be avoided. I don't think I'd do those anyway because of the potential mess. They are bad enough on dry land.
