neon goby

[prison police]

I had a breeding pair of neon gobies. (I had) I noticed the one going in and out of holes in my reef live rock. Now not seen it for about a week. I do not know what happend. My question is, Is there any way to tell a male from a female? I want to replace the one missing. These guys were wild caught and the divers staighted they knew they were a pair because they darted in and out the same hole and stayed close to each other on the reef before the divers caught them. I got them home and sure enough they acted the same and swam alot with each other.PLEASE help with any info you have.Thanks Chad

There should have been a quite remarkable difference in the two fish with the female being much larger and more rounded while the male would have been smaller and sleeker.

A week is not long enough to panic, wait another week before giving up on the missing fish.

They are believed to be hermaphroditic, if you need another try to get the smallest one you can find, it should work out as far as I know.

Thanks David. Being in a 24g nano I figured I would see the missing fish some time. I dont even see it during feeding.Thanks for the reply. Any other info from anyone? Thanks Chad

Chad, I've lost a 3" Synchiropus stellatus in my 24 gallon..no bodies ANYWHERE!

Anyway, contrary to what David posted, I've heard that Neons are NOT hermaphroditic...which may may repairing yours more difficult (if you've lost one).

David, do you have any more info on the Neons and their pairing (specifically regarding sex changes)? I have a lone one myself I'd like to re-pair if I could!

Have to agree here,I think clown gobies Gobiodon are the only gobies reported as hermaphrodites.

Ah, actually I have to add in that the Greenbanded Gobies (Elactinus multifaciatus) are known hermaphrodites. I just haven't ever heard of it in the Neon Goby (oceanops).

I havn't read anything regarding neon's being hermaphroditic or anything. Just that you should get a small group in order to more easily obtain a pair. and fwiw, I had my last neon goby "disappear" as well, there small fish so any bristleworms and hermits and other cleaners will tear it apart and be done with it very quickly.

I think it is Gobiosoma?.Neons are Elacatinus,a related genus.
Where did you get the data from?

 

[aomont]

Fishbase Luis ! They put GBG under Elacatinus also but reporting it is protogynous.
But what happens to everyone I hear putting any two neon goby and getting a pair ?
And what is gonochorism ?

[aomont]

Never mind about gonochorism (= different sexes).
But still thinking on neon goby pairing...

If any of you are in contact with Todd Gardner you can get a difinative answer. I certainly don't know from experience but a few years ago I received 8 cb G. oceanops from Todd, 2 per bag and all were small juveniles. I left them paired as they came and lost one pair right away but the other three all went on to become spawners. I am 90% certain Todd told me "any 2 will do" but it could just be my CRS acting up
