They do look like the same fish from the markings around the eyes, but I wasn’t aware that they were taken so many months apart. The behaviour and algae growth on their surfaces can change a lot in that time. The description in Fishbase is quite good - thank you ChrisRoss, especially about the warty tubercles and pectoral fins (stargazer’s point backwards a bit more and can have spines on the gill covers). The white-ish coloured fish in diggy’s first photo is more likely a scorpionfish actually. I suspect maybe a relatively juvenile S. diabolus, although sometimes called a Devil Stonefish or False Stonefish. You can see the spine on the gill cover in the two photos of the stargazers.

Stonefish I suspect. Stargazers are so often buried, the ones I’ve seen don’t have the ‘debris’ developing over it.

Looks likely to be that. One of the photos here looks really similar. https://www.reeflex.net/tiere/9449_Paracentropogon_zonatus.htm I understand you can tell male from female from the dorsal fin. The finer spined ones are female, so this would make it a male. https://www.reef2reef.com/threads/two-bandtail-waspfish-in-one-tank.261400/

That’s unfortunate. I got it some years ago and don’t have a clear recollection of the details. I do have a vague memory that you only paid for one and the other two were free downloads. I’m not sure how you would find out more. I can see the same issue applies to me now too, when I look on the App Store only Vol.3 appears(so that might pose a problem for me should I upgrade my iPad in the future). I did find this webpage which links to the other volumes. See if that works for you: https://appadvice.com/app/reef-fishes-of-the-east-indies-vol-3/705229079

Yes I have the ebook version and use Bluefire Reader to view it on their recommendation. I prefer to navigate using search terms. It works quite well and you don’t realise it’s a PDF. fishid.com were really good and helped me transition to this new reader after their previous reader went out of business. I have both Fish ID and Creature ID for Tropical Pacific on an iPad and iPhone. So much more compact and light than packing books in luggage that I did before! There is also a three volume fish ID book called Reef Fishes of the East Indies. This only appears on the App Store for iPads. https://apps.apple.com/gb/app/reef-fishes-of-the-east-indies-vol-3/id705229079 I can’t remember the details but think you buy one volume (as an App) and then download the other two free. Each volume appears on your iPad as a separate app. https://m.facebook.com/pages/category/Book/Reef-Fishes-of-the-East-Indies-440116506076969/posts/ Good luck!

Not an expert, but that looks more like a sponge to me [emoji1744]

How about the Starry Night Octopus? Might be more typical of that part of the Pacific.

Agreed not fangblenny. Good call on E namiyei. Have a look here: http://fishesofaustralia.net.au/home/species/1904

Sailor's eyeballs was another given name I believe. The more polished one can give a nice miniature reflection of your camera rig in the water. I have seen one disappear in the time between dives and I understand that they reproduce and disseminate by popping.

Upturned mouth - should be more like a stonefish to me...

... although I would be interested to hear from Bart if these spots ever occur in the lower half of the body.... Sent from my iPhone using Tapatalk

Bart is right. A useful clue is the ocellated spot (sometimes considered false eye) which is in the upper part of the body near the tail. Sent from my iPhone using Tapatalk

Not an expert, but I think they're called Hammer or Anchor Coral (Euphyllia ancora). Sent from my iPhone using Tapatalk

I'll make a start: The one that 'should be easy' is a checkered snapper (Lutjanus decussatus) Sent from my iPhone using Tapatalk
