As this island also serves as sea turtle conservation park, if you are lucky, you may also find baby turtles which were going to find their way to the ocean after birthed. If you come on the right season, it is also possible for you to witness a turtle breeding during the night.
Personally, the atmosphere that this island offers is so awesome since it is guarantee that there will be not much people available there during sunrise & sunset. The resort is made private & it also has a decent dive centre to accommodate your underwater passion. Have I been there? Of course! Have I stayed there? Of course.. not. It is just out of my budget. Anyway, I was traveling solo, so why would I spend a lot of money in a deluxe cottage just to be - alone..
Besides for its wonderful white sand beach, Sangalaki has Manta Point which will give you around 80% chance that you will encounter the mantas. I’d say 80% because under the water, there is no such absolute certainty. I dived there 2 times during that visit and I met only around 3 mantas during the first dive, then I was greeted around 20 mantas for the 2nd dive.
Somehow, it will be easier to meet that manta if you do snorekeling because you can see clearly their wingtips. But if you are dropped at wrong location, or when you are just not lucky enough, you’d meet none of them - just like what my friend experienced when he dived on that spot - to see nothing. Correct that nothing is able to give you a warranty that you will meet manta, but from the experiences of the divemasters there, the chance is quite high and it is worth to try. At least once if you plan to dive in this archipelago.
