Yes we did every night dive... Saron shrimp and pygmy squid etc. Walls/reefs are never my favorite night dives. I will always prefer a good muck/critter night dive. I don't mean to be negative it is just that there are better places to dive in Indonesia. When we went to Wakatobi it was on a liveaboard and we had just gotten done diving Alor which is WAY better than Wakatobi so it was just kind of a let down. I think it is a great place for someone who has never been to Indonesia... honeymooners etc. or someone who wants the fancy resort feel. Good luck!
