Sea Robins (actually Gurnards)
I hope you don't think I'm picking on you by sending emails when I see
mistakes! It's just that next year I'm moving and am going to get a 250
gallon tank, so I am constantly surfing to see what my options are,
fishwise. The more planning the better, including with regards to order of
specimen introduction.
That said, I humbly point out that the photo you have in the new Sea Robin
section is of the fairly closely related _Flying_ Gurnard, Dactylopterus
volitans (often confused with D. orientalis in the trade). The regular
gurnards and flying are both hardy, but unfortunately the well-named flying
gurnards like to go carpet surfing. (One specimen got all the way from the
living room to the kitchen one time, found it only after spending an hour
looking for the body). (http://www.wetwebmedia.com/searobins.htm)

<Mmm, so, what is your correction, addition? That dactylopterids are escape artists? Or the id? Will check on the morrow. Bob Fenner>

Sea Robins
Hey Robert,
Love your site. I spend most of my time reading everything you have to offer about anything marine related.
<Yikes... most of your time? It takes me hours a day to produce it...>
I have a question regarding Sea Robins that I'm hoping you can answer. I cannot find very much information about this specific fish ANYWHERE.
<Try fishbase.org on the Net for scientific info. on the family, species comprising the Triglidae.>
Do you know why this is?
<What I call the founder (flounder?) effect... not a commonly used group of fishes/livestock, therefore not requested of collector/divers, therefore not sold on the market, therefore not a commonly used group of fishes/livestock...>
From what I can tell it is a pretty common fish in the ocean, but apparently not so in the hobby. 
<Mmm, not common in the wild (as far as I know, have heard, seen), and almost absent from the trade>
My LFS has a very nice (4 inch) Sea Robin that has very bright light blue edges around the 'wings'. I am not sure on the exact species, and even if I was I'm still sure I couldn't find good information about it. I am very impressed with this fish, and would love to bring it home. Normally I will read 500 things about any fish I am considering, and then decide. In this case, I cannot find enough information about this fish to make an informed decision. Can you please tell me the basic info regarding this fish? (Size, Compatibility, History, why it's not popular, eating habits) I have a very aggressive tank, puffers, triggers, wrasse. It's a 100G tank, the only thing I've gathered is these Sea Robins may get large.
<Mmm, looking over my otherwise enormous Scorpaeniform (the order that includes Sea Robins) files, I find just one pet-fish piece: by Aaron Norman (yes, same great aquarium photographer), run in Marine Aquarist Magazine in 1976 (7:3)... reading through this and my scant knowledge of when our stores carried such exotics, and chatting with public aquarium workers (these are current darlings)... I can say little with confidence. Look for initially undamaged/healthy specimens that are feeding... make sure the ones you're considering don't get too big (check on fishbase here at species level, likely the genus Prionotus)... and make sure the fish/s/es are getting enough to eat. Sea Robins, aka Gurnards, Tubfish are good feeders, but you have a tankful of competitors. Bob Fenner>
Thanks for your time.
