After far too long away from fish breeding, I think I'm going to give these little guys a shot. I had my fish guys order in a pair for me and picked them up last Wednesday. Acclimation seemed to go fine. They are in a standalone tank of about 10 gals. (it's an old acrylic sump) right now, in case I need to dose them or anything. Tank mates at the moment are one snail and three small bristle worms.

I found their pair bonding to be pretty interesting. After being in the tank about 10 mins., the two finally found each other. After some sizing each other up they had this little bonding moment, after which they've been completely inseparable: The first night they found the cave system that I made for them and I haven't seen them out since. They mainly sit next to each other at the opening of the cave where the current brings food right to them. So far, they seem to eat everything I've tossed at them. Apocyclops are a big hit, as well as TDO C1 and my homemade fish goo.

Good luck! I've been waiting for a pair to show up on my LFS' fish list for awhile. They put two "randoms" in together for me to see how they would get on, and they got to fighting, so we figure they are males. So I bought one, and am waiting for another one to arrive in hopes it will be a female. My assumed single male is a good 2.25". So I'll be on the boat with you soon.

As far as breeding research goes, it looks to me like Bandeng has had the best luck of anyone I've seen so far. His breeding thread is here, with tons of great information: http://www.marinebreeder.org/forums/viewtopic.php?f=222&t=707&sid=87b7246098ca9469c36d4d09f8ffeefb It looks like the highlights are: They spawn roughly every 8 days. He was able to keep the larvae alive using one of two SS strain rots. Looks like he finally got several settled juveniles at about 1 month, but that's about as far as he was able to get.

EasterEggs: It sounds like they should be easy to pair. The males have a black dot on their pelvic fins. The females do not. I've seen several photos of pairs that look like this and it was mentioned in the paper introducing the fish.

Excited to see this. I have had my eye on these guys for a while. Going to get a pair coming up here before long.

Well, they certainly are pretty little gobies. I hope mine eventually start coming out more. It doesn't look like Bandeng tried copepods with them, so I'm interested to see if the babies like Apocyclops.

I was going to ask what copepod you were going to try. I haven't done any research yet into which one I wanted to try. I fell in love with these guys the first time I saw them at my LFS several years ago. They are on my list of the best looking marine fish available.

I will look up some photos. EDIT: Looks like I have a female, and the other one at the LFS was female too.

waldend: Thanks! Sorry I missed your last comment above earlier. Well, I'm going to try Apocyclops because that's what I have lots of. But there's always the option of getting a batch of Parvocalanus in from Reed's as a starter copepod to get the larvae up to a size where they can eat Apocyclops. Having Apocyclops available as a second (hopefully first, of course) food seems like a pretty decent plan to me. Of course, I'm open to suggestions....

Are you going to go au-natural and let them spawn in caves/under rocks or go for pvc tubes? (or a combo of all of em?

If they are fine under the rocks then I am, too. It's really not much: A couple of dome shaped rocked propped up off the bottom with a couple of coral skeletons on top. Easy enough to see under.

I took these over the weekend and forgot to post them. This is the female. She found a den on the backside of the rock work where food blows right to her so she hardly leaves. Hopefully she will get more bold. Here's the male. He's now getting good about coming out for the first feeding of the day and is generally less skittish. He looks like he's getting a belly on him. He wasn't too fond of the photo shoot, so he's hiding under a rock, too.

I think your plan sounds good. I have been excited about Parvo ever since Witt talked about using them at last year's MBI conference. I will be trying to start a culture after the first of the year.

Oooo. I haven't heard about Witt's talk. Can you paraphrase for me? They ought to be good. I would think they would be a good size to be first food for mid-size larvae (i.e., those too small to take rots but not so small they need Parvocalanus). I would also think they would make a good second food for the really tiny larvae like dwarf angels. But, we'll see. Anyone know which sex broods the eggs in these? I would think the male, but that female just does not budge from her little den, almost like she's sitting on some. I doubt she was in shape enough to spawn already (she looks too thin in that first photo to me), but I wonder.

Unfortunately I cannot paraphrase. I didn't take notes last year and it has been a long stressful year since then. I do, however, recall that he used them for the work he was doing and I felt he seemed very excited and optimistic about it being a good copepod to use for marine ornamentals. This was the feeling that stuck with me and made me want to try them. Sorry I cannot be more specific. If anyone recalls differently or can expand please do so!

Thanks for what you have given me. I knew that they had been used before and I've used them now (not exclusively) for clowns. I just hope that the dinoflagellate diet is enough to get some tougher fish through. Well, never know 'til I give them a shot.

The male had taken over the female's little cave for a while, never leaving that I saw. Today he is out of the rock work and running around the tank, displaying like crazy toward the female. I think they probably spawned and eggs hatched last night/today. So, the watch begins to try to figure out the schedule.
