Yellow Watchman Gobies have spawned - what to do?

[eww]

We just got back from a week long vacation and it seems our pair of Yellow Watchman Gobies have spawned. I think we have a male and a female. We obviously have a female . The larger of the two turned white/grey before we had obtained them. Anyway there is a sac about the size of a very large grape hanging in a hollow under the rocks. The fish that is still yellow is almost constantly swimming around it in circles. Is there any way for these to hatch and raise them or are they just going to be fish food? The place the sac is would be VERY difficult to reach to try and remove it or do anything with it. Any input is greatly appreciated.

Do a search for myteemouse a's he had his watchmen gobies spawn. I don't know how far along he is but lots of info there

you'll need to get not rotifers but SMALL rotifers (very hard to find) and pull the eggs and treat them like clown eggs..

OR put the breadding pair in there own tank and go that route but the SMALL ROTIFERS is key.

I don't know what "treat them like clown eggs" even means. We are really new to saltwater in general let alone trying to breed fish. I caught one of the fish this afternoon in the trap and moved it to the QT but I don't know if I'm going to get the other very soon as it doesn't stray far from the eggs.

here is the BEST info I found on the breeding of yellows.
VERY informative and good read of an article. and background

food you will need
(quote from article)
After giving up on the clam trochophores, we went in search of the elusive S (small) strain rotifer (Brachonius rotundaformis). A lot of information about these rotifers is available on the internet, but very few vendors actually stock them. One aquaculture facility in Canada claimed to have them in stock but "not enough to spare." We then contacted the Oceanic Institute in Hawaii. It had some really helpful people, who sent us some of what they had of their S-strain rotifers. The problem we ran into, however, is that there is no such thing as overnight delivery from Hawaii to the east coast of the U.S., and this was in the heat of summer, so the cultures we got from them did not survive the transport.

I have to say one of the best things about being on Reef Central is the relationships you build with all sorts of people. We finally received a hot tip from a Reef Central member as to where we could track down a source of S-rotifers. I contacted this source and very soon thereafter had in my hands a vial of B. rotundaformis cysts. We followed the normal protocol of hatching the cysts and starting a culture, and this went flawlessly. From the information we found in earlier internet searches, it was said that the S strain does best at high temperatures, around 95°F.

Wow. I don't think we could even attempt this with this batch. They will probably be hatching soon if they only incubate for 4 days. We noticed the egg sac on Sunday when we got home and have no idea when it was actually created. A source for the S Rotifers isn't named either.

Have you had any luck doing this Adam?

Thanks for the info anyway.

no luck
I really haven't tried because my yellows are in a low down deep tunnel made by a pistol shrimp and there is no way to get the eggs out..
the one time was an accident I was cleaning the tank and I think the od change of current knocked them loose.

 

[eww]

We must be doing something right as these two have spawned again only this time they are in their own QT. The eggs were there this morning so they had to have been layed last night. We would like to try it this time around. Anyone know a source for the SMALL rotifers?

oh my..congrats...as long as I've been in this hobby, I've never experienced mating in the tank...I am hoping the pair of occelaris clowns I have start in the next year or so...
