my plec loves lettuce, but my concern is with how often should i feed it?
They can eat lettuce but it doesn't have a lot in it nutritionally. You are better off using dark green leafy veges like spinach and silverbeet. Also pumpkin, zucchini, cucumber, apple, etc. Try to vary the diet so they get a different food each day. If used in conjunction with other foods, lettuce is fine once or twice a week.
