He looks familiar but I can't quite put my finger on why...
 
Not DD, but my local guy snapped me pics of this golden hawk fish at the wholesalers today

I should have gotten the other one they had a few weeks ago. With this one I would have had a pair.

They still have him. Pairing Marine Betta is not as easy as it seem. It took me several try and long time nursing torn find (so I can return a whole fish back to the LFS) before I come up with two that tolerate each other. One of mine is still immature. My hope is have a pair once both fish mature

It is super easy if you can tell male from female - in the past I put 3 adult pairs together and they were usually spawning 2 to 4 weeks later.

Another way is to put a juvenile together with an adult or sub adult. Since females can turn into males and they don't need to bond like clownfish or other pair forming species it's really easy. The downside of this method is that it may take years before they spawn.

Several juveniles should work as well if the tank is large enough.
 
How can you tell? Do you know for sure that they are hermaphrodites?

all I know is that some (juveniles) fights like the fresh water Beta males, while other tolerates each other. My tank is large 320 gal and 450 gal before

Anyone have info on these guys (Caribbean Clingfish)? I am setting u pa Caribbean biotope soon and it seems like it would be a nice addition to the tank.

I'm pretty sure they are protogynous hermaphrodites (female -> male), though I haven't actually tested it by putting two known females together to see if one changes to male. But juveniles I raised developed to be male when raised alone or female when growing up in the presence of another dominant specimen.

Males have clearly longer pelvic fins and their heads are rounder.
 
Thanks
Royal Gramma are also dimorphic with similar characteristic. In RG the male have clearly longer pelvic fins and the the purple area is larger
