Unique Yap Manderin Fish Coloration?

We have ourselves a latent discovery that’s currently “under investigation” – do Manderin fish in Yap have a unique color pattern?

This was first noticed by a guest of ours, Michele, who has photos of Manderin fish from all over the world including other Micronesian islands. Her own curiosity of her photos lead her to Australian PhD and head fishologist, Dr. Gerry Allen.

In an email response, Dr. Allen said: “Indeed, something is not right as far as that Yap fish is concerned. I’ve never seen this species with the “reversed” colour pattern. I can only conclude that it is a rare colour variant.

Michele asked the dive staff to be on the lookout for the reversed color pattern Yap Manderin fish. For those of you who have been here and went on one of the nightly Manderin fish mating dives, check your photo collection to see if you have shots of the backwards Yap color variety of mating Manderin fish.

Dr. Allen is a past President of the Australian Society for Fish Biology, an honorary foreign member of the American Society of Ichthyology and Herpetology, and a recent recipient of the prestigious K. Radway Allen Award for Outstanding Contributions to Australian Ichthyological Science. Gerald R. Allen is the author of:

We stayed at the hotel and dove with Manta Ray divers in early December 2017. The hotel is very comfortable, well run and staffed with wonderful employees. During our visit my wife came down with an illness and the consideration and support from the hotel and dive staff could not have been better.read more

The staff couldn't be more friendly and accommodating. Food is good, (worth upgrading to include all meals). Diving is good too.read more

The best place to stay in Yap. The resort is really nice and clean, the scuba diving is great, and the docked ship that houses the bar, restaurant, and movie screen is very cool. I really enjoyed my stay here.read more

The whole place centers around the scuba diving operation. Probably better to find somewhere else if you're not a diver. The dive operation was generally good, but a little too laid back - schedules weren't always clear, and sometimes would change without any notice. Sometimes it was hard to tell if this was really because of changing tides/weather or because of the island pace of life. Pizza is a surprisingly good option at the restaurant.read more
