It's not iceberg lettuce! I know that iceberg lettuce does not have nutritional value for tortoises. I give him a diet of darker lettuces. I use a 50 gallon rubber maid tub for his enclosure but I will upgrade when he's at least 5 inches.
Just a quick question... What do you feed Marty? I feed Thor a mixed diet of grass, weeds, dandelions, and standard lettuce.... Good luck with your phone by the way!
