  1. This is correct. The image, and behaviour, look different because it is a juvenile. Typically there would also have been a pair of adults in the anemone.
  2. The first one are juvenile cardinalfish. Could be wassinki or the very similar cyanosoma. Did you see adults nearby? The second looks like a kind of scorpionfish but not one I know The third is a ghostgoby, most likely Pleurosicya mossambica The fourth is a female shoulderspot wrasse (Leptojulis cyanopleura)
  3. Image two shape and eye colouration resemble the ghostgoby (genus Pleurosycia). I can't find one with a clear match to your image with perhaps P. carolinensis getting closest. It is known from Luzon so could be in Anilao. Juveniles are always hard to ID because reference books often don't have pictures for them. Image 4 may be a young lizardfish based on eye position and mouth/lip colouration. Image six looks like a juvenile kashmir snapper to me.
  4. It looks like a Tomiyamichthys species to me. Most similar to T. lanceolatus but they typically have two dark spots on the back of the first dorsal fin (there is actually a picture of one from you on the internet). I don't know if the black spots can be absent based on behaviour or gender but I don't see good alternatives.
  5. I thought I'd just update this old threat with the announcement that the "rhinoceros blenny" turned out to be a new species, as well as a new genus, of goby that has just been scientifically described as Cerogobius petrophilus (horned goby). With Ceros referring to horned and petrophilus, "rock loving", referring to its habit of living in small worm holes in rocks. They comment on it being the only goby with a single 'horn' on the mid snout and point of the similarities in behaviour and anatomy with blennies that occupy small worm holes in rocks. Here is the citation but the paper is unfortunately not publicly available. Zootaxa 4565 (2): 171–189. March 8, 2019 Cerogobius petrophilus (Perciformes: Gobiidae), a new gobiid genus and species from the Red Sea MARCELO KOVAČIĆ, SERGEY V. BOGORODSKY, EMILY M. TROYER, LUKE TORNABENE
  6. This is Crossosalarias macrospilos, or the Triplespot blenny.
  7. I am interested in this as well. One requirement is to get enough light for the exposure and Jack's test is promising. Another is to get enough light to 'compete with sunlight' which I expect will work at least for objects at close range. Regarding the former point, does anyone know if this LED ring light flash pulse is as short as conventional strobes (so much less than 1/250th of a second so illumination is independent of shutter time). If the LEDs give a longer (let's say 1/20th of a second) pulse, and technically I think they could without overheating, greater illumination can be achieved by using longer exposures up to the flash pulse length. In other works, would Jack's shot at 1/125 sec have been brighter/dimmer at 1/60 or 1/250, respectively. Another question: youtube videos seem to suggest you can run the ring in continuous mode and still use the pulse flash. If so this could be both a focusing light and low-power strobe.
  8. Here are two shots of the Oplopomops-like goby. Found at 4-6m depth on fine sand/silt with seagrass in Marsa Abu Dabbab (25.338 (lat)34.74 (lng)).
  9. Thanks Emily, that is great news. Definitely deeper than I and Alex found them and on the Saudi side of the Red Sea. I found mine near shore but I think Alex also found them on an outer reef. My problem has been that as a hobbyist I couldn't easyly get paperwork to catch and export fish so it is great that you can do this. There is also a new Oplopomops goby I found in a seagrass field in the Red Sea that Sergey would like to get specimens off. I can dig up an image just in case you've seen it. Or sometimes just knowing about it makes it harder to see and recognize.
  10. Wow! I've been distracted with freshwater aquariums and breeding cichlids so hadn't checked wetpixel for a while. Boy am I glad I did tonight. I would love to know more about the location and habitat where you found them. Your images show two separate dorsal fins so it appears to be a goby after all. I would not be surprised if it is a brand new genus and wonder if you'd be willing to donate the specimens to science, perhaps that is why you caught them in the first place. Bart
  11. I learned something new today. Thanks. Very cool how nature keeps surprising us.
  12. 3 seen things like this in the Red Sea and thought they were a juvenile dartfish but also check out the shortfin minidartfish (aioliops brachypterus) 4 probably silver demoiselle (neopomacentrus anabatoides) no luck on the others though the bottom two are probably obvious if you've seen them before.
  13. 1 peacock fairy-wrasse (cirrhilabrus temminckii) 2 juvenile batu coris (coris batuensis) 4 blackspot damselfish (pomacentrus stigma) 5 wolf cardinalfish (cheilodipterus artus) 7 lemon damselfish (pomacentrus molluccensis) others already correctly identified
  14. 1 looks like lined chromis (chromis lineata) 2 juvenile bird wrasse ( gomphosus varius) 3 threespot dascyllus with acne ( D. trimaculatus)
  15. #1 is linecheecked wrasse (Oxycheilinus digrammus) #2 is a blenny, most likely a Cirripectes species but can't tell more from this shot angle #3 juvenile spiny chromis (Acanthochromis polyacanthus) #4 is definitely a dragonet. Either S. morrisoni as suggested or S. bartelsi (Bartel's dragonet). A shot from the side might be more conclusive. #5/6 not fish
  16. Hi Dave, I certainly have never seen this in other parts of the Caribbean and I never heard about it before. So thanks for the post. As to what it means ... just one more underwater riddle that keeps diving so interesting. Bart
  17. I used to use two strobes in the past but prefer the simplicity of a single strobe. A more honest interpretation is that it takes more skill, thinking and "aesthetic awareness" and I simply don't dive enough to master all of that. It may be different for WA where just have a wider beam angle itself is helpful. If you are on your first UW photography trip I think you will find there are too many things to experiment with already. No need to get all the gadgets all at once. Another tip, if you can find a place with a house reef where you, with or without buddy, can dive without dive guide you can much more easily experiment with camera setting, strobes etc.
  18. The worst thing is to buy something too cheap that frustrates to the point of turning you off on what could have become a great hobby. The next worst thing is to buy something so expensive and elaborate that it turns you off, or simply confuses with too many choices to figure out on a short diving holiday. Fortunately there is a whole lot in the middle. I would consider getting just the housing, one strobe and no macro-converters, snoots, and what have you. You can add a second strobe on the next trip for better wide-angle and macro converters if that becomes your passion. The Nikon D7200 has been around awhile so you can also look for second hand housings and use the savings to add a focus/video light. PS: welcome to wetpixel
  19. Autofocus, including tracking subjects, and viewfinder are the two most important features for me and both are improved. Especially compared to my current EM5 mk I. Focus bracketing would be interesting for macro if we could use video lights instead of strobes and I have the feeling that video lights are already up to the task in at least some situations: macro/close-up and not shooting in bright daylight. A narrower beam video light may help as well. My next trip will still use the EM5 but I am looking forward to hands-on reviews to see if the claims about the AF translate to real-world experience.
  20. No. 1 is obviously some sort of scorpionfish but I couldn't find a convincing match No. 3 the general shape and first dorsal fin point to a dragonet, but again one I can't place No. 4, starting so sound like a broken record, clearly a cardinalfish but not one I know. Very likely genus Ostorhinchus No 6, juvenile barracuda of one kind of another, but don't have ID books for juveniles. Sorry I couldn't be of more help and thanks for sharing Bart
  21. The lizardfish is genus Saurida based on the mouth shape. Species can be S. gracilis or S. nebulosa. Hard to tell apart. Number 3 looks somehow familiar but I can't place it. Might it be a night coloration?
  22. A Canadian mining company, Nautilus Minerals, reached an agreement with PNG several years ago to mine deep sea vents at 1.5km depth in the Bismarck sea. This would be the first ever deep seabed mining operation. In their environmental impact assessment they compare their mine with three others, all of which are land-based. Guess what; the deep sea operation is predicted to have little impact on land-based criteria such as effect on forests, fresh water, food supply, etc. For other criteria, such as presence of organisms of medicinal value, they claim no impact because no studies exist (more likely none have been carried out) that prove such organisms exist. They also score very good on a third set of criteria simply by claiming that, yes effects will be present (for instance habitat disturbance) but it won't affect us as no one will see it. What is all but absent is analyses of effects that would be specific to the (deep) ocean environment. Nothing about expected levels of chemicals and particulates released into the water and the impossibility to contain them. Nothing about currents that may carry contaminants to nearby shores. It is of course possible that deep seabed mining has much less impact than land mining but I am very uncomfortable with this development as we are only just getting a glimmer of understanding of the deep sea biotic and abiotic world. In addition, oversight of land-based mining is already poor and I can only imagine it being much worse when it is out of sight. Finally, if it was just one small operation, they claim just a few hectares, then likely the impacts will also be small but by now 19 licenses for deep seabed mining have been given out and that is unlikely to stop. The BBC already reported on this in April 2014 (http://www.bbc.com/news/science-environment-27158883). Nautilus Minerals has posted its reports online (http://nus.live.irmau.com/IRM/Company/ShowPage.aspx?CategoryId=438&CPID=1586&EID=37434714&masterpage=31) the one I read is named "Discussion of Impacts of Solwara 1 and three comparison mines" (http://nus.live.irmau.com/irm/content/pdf/eartheconomics-reports/15.pdf) Nautilus Minerals would probably claim this should not interest divers because it is well below safe diving depth, but I hope many of you at least want to know about this. You may also be interested to know that AVAAZ started a petition to target investors that are needed to finance the project.

  23. I personally strive for zero damage, while accepting that some damage is implicit even if only by increasing economic development near shore. The closer you want to get to the reef the better your buoyancy has to be. So either keep a distance or perfect your buoyancy, although not necessary by PADI or other course. Do not touch any LIVING thing underwater. One or two fingers placed on a carefully selected piece of dead coral just to stabilize, no force, is much better than jojoing and kicking your fins to stay in place. You could do this equally well with gloves and the whole no-gloves rule is imho just because people expect you to be more careful without them. If you ever see parrotfish scraping the corals you also realize that if corals could not handle any mechanical contact they would have long been extinct (not an excuse to be careless, just some perspective). I don't like diving sticks, assuming you mean the metal pins, as you don't get any tactile feedback and you create a point-pressure unlike a finger with or without glove. Buddy signals to help each other out of a tricky position sound complicated to me. You really should not get into such situations in the first place. Tucking away any dangling pieces of equipment is a good point as are most of the others. In the rare cases that I do touch the reef it is virtually always my fin tips. Retracting your legs while stopping finning and using your hands and/or lungs to move away from contact works well. I also make an effort not to kick up a dust storm when swimming close to sand substrate, but I have no problem touching or even lying on the bottom after ensuring it is "clean sand". Bart
  24. The first is a grouper. I am not familiar with those waters but the same species for the same location is shown here http://www.alamy.com/stock-photo-starry-grouper-epinephelus-labriformis-socorro-revillagigedo-islands-59071706.html and named starry grouper, Epinephelus labriformis. Many other images of this species have more obvious starry white spots so you may want to double check but my feeling is that it is correct. bart
