There is Turtle Traffic, which for my experience is the easiest spot to encounter a massive amount of sea turtles. Fussilier spot certainly means that you can get a good chance to meet fussilier schooling. Other spots like The Walls & Coral Garden provide you an exceptional looks of coral reefs. Then you shall visit Channel, a site that claims to be the most excellent dive spot in Maratua for some reasons. This spot is basically a channel which connect the inner & outer seas in Maratua Atoll. This means that the current is always strong at this area & you know well that big fishes love current.
During the initial phase of low tide, the sea flows from inner side to the outer ocean & vice versa. By bringing a relatively dirty water from the villages, diving during low tide is not a good option since the visibility is worsen. Hence the best alternative is to reach the area just before the high tide when the flows are bringing the seawater from outer ocean.
Turtle Traffic - Located nearby Payung-Payung village, this spot is commonly dwelled by a lot of turtles. During my last dive there, I could spot around 15 of turtles just in one dive.
With an enormous strong current, dive at Channel will be quite unique. Crawling at the seabed to get to the best spot, we grab to the strong point then we stop & look up to see all the big fishes hold their position on the cleaning station. It is the place when all the fishes come to wash their body with the current. It is like to watch them all from the aquarium, wait, we are even inside the aquarium itself. Depending on your luck level, you basically can see any type of big fishes here, especially for a great amount of barracuda schooling. I'd like to suggest that you definitely shall try Channel if you happened to visit Maratua.
OOH MY GOD!! ANOTHER CLOWN FISH?!
