what is a good way of feeding lettuce w/o a clip?

so lettuce won't go bad as quickly as zucchini?
 
You could could stick it in some boiling water for a few seconds. Works for me.

I really wouldn't leave it in the tank for more than a day, day and a half for the fact that it starts to get ratty and whatnot...

As suggested, boil greens for about a minute as this will help soften them and allow the fish to more easily break them down.
 
its been in their for a few days now, and my fish still peck at it.
