Sorry, I usually sit back and let others have a turn ... but I was bored with what I was doing at work! I'll let you post again floridafishman, as I probably won't get a chance to do anything for a while. Glad you are keeping them. It looks like a nice fish, though probably not a good one to...

Belted sandfish - Serranus subligarius.

Muraena pavonina?

Halichoeres prosopeion

It seems like we are each doing our local species! Nice one.

Yes, Hephaestus carbo ... known locally as a coal grunter. Your turn.

No, not a Macquarie perch. It's in a different family.

Freshwater Australian.

OK. Here you go.

There are several very similar species in Canthigaster (sharpnose puffers or tobys) with this kind of coloration. I can't really tell which one you have without seeing the tail. If you could post a photo showing the tail, I should be able to get it to species. Tony

BTW, I'm sure Gillie is right - just waiting on confirmation from Fishperson.

There's a bit of confusion going on it seems! My guess was for the cardinalfish, whereas Gillie's guess was for the tetra. The tetra photo was posted because there were no guesses posted for the tetra (at that time - I posted a guess after the tetra photo was posted). So, we are waiting to see...

Many, if not most, dottyback species change sex (or more correctly, are simultaneous hermaphrodites that allocate to one or other sex). The colour changes that are observed in many dottybacks is probably associated with sex change. However, I have been reluctant to link colour to sex for many of...

I should point out that there are two other species that are closely related to P. elongatus. One (P. striatus), is readily distinguished in having dark lines on the body. The other (P. fuligifinis) is much more difficult to separate from P. elongatus. Mostly it has darker fins - though you...
