while looking at lettuce nudi's i found out that they dont do well in small unestableshed aquariums i was wondering if there were any nudi's that can go in a 11g?
Lettuce nudibranches and basically all sea slugs are specialize feeders meaning they only feed on one thing only.
Sorry,I don't recommend any nudibranch in any size tank unless you have serious hair algae and bryopsis algae problems or severe aiptasia anemone outbreaks.
