    Need a second opinion on this one. Caught this guy on Friday thinking it was a Dendrochirus zebra. Now that I've had a second look I'm going with Pterois mombasae. Pretty sure it's not a P. antennata. My similar sized P. antennata has longer pectoral fin rays, a smaller eye and far less black at the base of the pectorals.

    This is actually the most brightly coloured lionfish I've ever seen...really quite a beauty. QT tank pics in crappy light don't do it justice:

    ive done a little searching for you and I am not certain thats a P.mombasasae. the eye seems to be too small and pectral fins have too much webbing. I stumbled across this site http://stockfootage.bubblevision.com/stockfootage/Pterois_Mombasae which gives 12 different vids of different P. Mombasae you can have a look at.

    i'll keep having a look....

    5m. I know it's shallow for the species, but it's a very protected area where I've caught several other deepwater fish before.

    P. mombasae seems to have more quite a bit more webbing than P. antennata, but not as much as a Dendrochirus. The Dendrochirus I've seen have all had basically just webbing with the fin rays hardly extending past it, like this one:

    There are really only 2 species with such colored fins, the P. antennata and the P. mombasae.

    If you say that it is not similar to your antennata, then surely it must be the mombasae? In all my books, I could find only 1 reference to the P. mombassae, and I could not verify form the angle of the pics. According to internet info, it does resemble the P. mombassae.

    Judging by these pictures I would have said P. antennata

    Lovely fish.

    It is pretty similar to P. antennata. I've got the luxury of having the two side by side in holding tanks and they look quite different though. Most obvious thing is the pectoral rays extend over twice as far on my antennata. The spots on the pectorals are bluish on the antennata and there is only a single row, other chap has several rows of black spots. General colouration (not the most reliable for ID, mind you) is very different, the new guy is quite a bright red, antennata a lot more muted.

    Not discounting that it could be a weird antennata morph, of course.

    but i don't think P mombasae has such long tentacles above the eye.

    Thought so too and that's what Smiths says, though if you browse pics on the web it seems that most seem to have long tentacles. Could be a case of juveniles having them and then losing them as adults like P. miles does. Mine is about 6cm long, so still quite small. All pretty confusing...these are listed as P. mombasae and they're from reasonably reliable sources:

    My money is on the P. antennata, having caught lots of them in the past.

    Having had a better look at the pics and the interweb, I am changing my mind and going with P. mombassae. The only real difference between the two species is regarding subtle colouration on the pectorals - P. mombassae's on the LHS and P. antennata on the RHS : [​IMG]

    lol...'once you learn to spot the differences in their spot pattern, the mobassae and the antennata are easily distinguishable...' yeah right! pull the other leg its got bells on it!

    Yes I see it - once you start looking for it, the difference is really pronounced, especially at the bottom of the pectorals.
