Just to close this one off - I asked Fishbase if they had an expert to whom they could refer this ID . The photos have now been seen by Dr Jeff Williams in the US and Wouter Holleman in Zambia. Both have advised it is not E. mirabilis but E. tutuilae, the High-hat Triplefin. They say that the whitish first dorsal and the white bands on the other two dorsals running onto the body are diagnostic. Apparently it is a complex species with versions present in the Red Sea, west Indian Ocean, Gt. Barrier Reef, as well as Indonesia. Further work is needed to clarify and sort them out.

 

Thanks again Bart

Everything Steve says is spot on. I have had my 45 degree (Inon on Aquatica) for about three years and would never dive without it - wide angle or macro. I found aiming it a pain to start with and also kept banging it on my mask due to it projecting rearwards quite a way. The one thing I have never quite mastered is viewing vertically downwards - say to get a view of the body shape/camouflage of a flatfish resting on the bottom. Fortunately this happens rarely and the full frame, bright image, low angle advantages make the whole thing very worthwhile.

Nigel & Bart

Have followed up your suggestion and done a lot of work on it. I'm sure you are right. Many thanks - would never have got there without you

Many thanks for your trouble Bart - most useful. Had a look round and can find even less about E. flavoccipitis. I have a couple of shots of the heads of mirabilis and there are no yellow/gold specks at all. Might try asking R. Fricke who described the species.

 

Your tome is excellent. It is available on iPad (which I don't have) at a very reasonable price and was supposed to come out for Android (which I do have) last May but has never appeared. Shame.

 

If I get any further with it, I'll let you know

Thanks Bryce

I had them down as Dragonets initially - Bartel's, Synchiropus bartlesi, seems the nearest. However, they don't seem to have the very accentuated mouthparts nor the skin flaps on the eyes to tie up with the photos. Hope you find something in your books or that somebody else chimes in.
