Goby Breeding Tips (Greissinger Gobies)

I do and would add whatever I could from the sea.

I need a new RODI filter. Before adding the fish would it be fine to use distilled water to keep the live rock live? Could it possibly kill any microfauna or bacteria or is distilled water pure enough?

Distilled or any fresh water is not good to keep live rock in. It needs to be in salt water, preferably from where you collected the rock from.

No, I meant distilled water only as a temporary alternative to RODI water (with salt then mixed to 35 ppt of course). Fresh water, especially distilled would probably do almost as much harm as leaving it to dry since it has 0 minerals or nutrients.

checkout this guy on youtube (he is a member here too) tons of great work and info on breeding a couple different species and raising them too

Bassooning, multispectral visualization, measurement, and sort of whatever else seems interesting.

Ok, I decided to take a serious approach to attempting to breed Greissinger Gobies. I have a shop thats going to order 2 or 3 from the supplier for me which is great because it means Ill be able to get them as soon as they arrive in good health.
The breeding tank will be 20 gallons and equupment will include a Noopsyche K7 Mini with wifi light, Bubble Magus skimmer, and an IceCap ATO. I have a chiller I can use but that probably wont be necessary.
Im going to use all live rock harvested from the ocean but dry sand since the bacteria on the rock should colonize the sandbed quickly. Since the rock will be ocean harvested, it'll be teeming with microfaunal prey such as copepods and amphipods to give the Greissinger Gobies a good start with a natural diet but Ill also supplement it with live Grindal worms.
I could have the gobies by next week but since ill be in the Philippines for the first week of September, will wait to order them until I get back.

I understand that one of the most difficult parts of breeding is supplying food to the larvae and young fish before maturity. Does anyone have experience breeding a similar species? If so, what did you feed the larvae and offspring when young?

Honestly, there doesnt seem to be a reason they havent been captive bred before aside from the availability and cost to buy multiple fish. I worked out a great deal with the shop owner so I want to take advantage of this opportunity.

Any tips?

Incredible species! One I always wanted to personally breed but never got any spawning luck from my pairs. I wish you the best of luck. The recommendations in this thread are pretty spot on, I would have both copepod nauplii and rotifers available for the first trials of breeding them.

Yes, that would be fine.

Distilled water should be fine. I am a setting up a new tank and have used distilled water 0 TDS salt mix and to keep my live rock.

I want the tank to be as mature as possible before adding the Greissinger Gobies so Ive just made the necessary purchases and am reading research related to the captive breeding of small goby species.

Considering adding SPS to the breeding tank after setting it up and letting it mature a little.
Opinions?

Also, gkt the live ocean rock. It came with tiny feather dusters and blue sponges on some pieces along with the beautiful corallibr covering it!

Here's how the tank is progressing... please pardon the fact that the tank is only 1/3 of the way full...I'm waiting for new RODI cartridges to be delivered and have been using distilled water in its place (with salt) so I'll fill it all the way once they arrive.

I added a couple more pieces of live ocean rock tonight, and added some coral rubble since I want the tank to match the natural environment of the fish as closely as possible. Since the rock came covered in coralline and has plenty of healthy hitchhikers such as small feather dusters, copepods and amphipods Ive been dosing phyto nightly to boost the microfaunal population and keep as many of the hitchhikers as healthy as possible. I'm already able to see copepods and amphipods on the glass which form a large part of the natural diet of the gobies.

Ive also taken care to make sure the microbiome takes root and fluorishes by ensuring the tank has adequate nutrients such as nitrates (by adding a drop or two of ammonia), amino acids, and vitamins naturally found in seawater. I didn't want to plunge rock from the ocean into a completely oligotrophic environment. I'll also be adding sand soon of course.

(I particularly like the natural hole in the middle of the biggest rock on the right).

The Greissinger Gobies will be added right after the shop receives them mid September. By that time the tank will have had a little time to become established enough.
