A list of hermaphroditic and gonochoristic (fixed sex) marine fish.

[Zionas]

This is what I know so far:

Hermaphroditic-
Clownfish (Male to Female)
Dwarf / Large Angelfish (Female to Male)
Hawkfish (Female to Male)
Wrasses (Female to Male)
Anthias (Female to Male)
Dwarf Sea Basses (Simultaneous) (Serranus)
Hamlets (Simultaneous)
Clown Gobies (Simultaneous)
Most Dottybacks (Female to Male)


Gonochoristic-
Butterflyfish
Dragonets
Cardinalfish
Jawfish
Blennies
Roundheads (Assessors, Marine Betta / Comet)
Firefish
Filefish
Surgeonfish (Tangs)

Actually, most if not all gobies are hermaphroditic. Including the fire fish.
Also many (I think all) sharks are Gonochoristic.

I see. Interesting.

Similar thread with potentially helpful info (I’m not at my computer right now or I’d go through and find what they have that you haven’t already listed - I know they discuss puffers too, so there is at least something different on it):

Hermaphroditic fish and non-hermaphrodite fish

Hello! I want this thread to help people figure out how their fish work as far whether they are a hermaphrodites or have seperate sexes, please if i mess up on something or you have something you want to add please add it. Clownfish: hermaphrodites start off genderless and become male, or...

Following along. Would be a good resource when looking for new fish.

I've found sources saying that, while some select goby groups are hermaphrodites, the vast majority are gonochoristic. Most of the hermaphroditic groups seems to be the smaller species in genera like Eviota (dwarf gobies), Trimma (dwarf/pygmygobies), Fusigobius (Fuse or Sand gobies), Lophogobius, Priolepis, Gobiodon (coral/clown gobies), and Paragobiodon (coral/clown gobies).

I’ll also add to that list Stonogobiops (Hi-Fin/Shrimp gobies), Koumansetta (Hector/Rainford/Hoesi gobies), Discordipinna (Potentially but it seems rather hard to sex them).

Also, Paragobiodon are also called the Bearded Gobies, some look really similar to Gobiodon but if you look at them closely they will have a more bearded look on their faces. The most common of this genus is the panda goby, paragobiodon lacunicolus

The stand-out one to me is Stonogobiops, as I haven't seen anything that says the same about the other shrimp gobies like Cryptocentrus and Amblyeleotris, maybe I just haven't looked deep enough. Still surprising given how much they can tear into each other.
