Meirz,
Begin planning that new, improved and larger tank. A YT might feel a bit cramped in a 33. I've got one in a 58 and I feel bad.
Anyhow, lettuce has little nutritional value. Get some Nori (dried seaweed) from your grocery store. Look for a brand without preservatives. Your YT will love it!
BTW, where are you in Israel? I get out there occasionally.
