Oh, excellent news! So far I've had no luck finding a Yasha with black on its pelvic fins.

So the guy's still out and about this evening. The girl's back in the small cave (that may be because I did a water change, though). Hopefully.... Sorry. Maybe have the fish store order one in for you? They should be able to specify.

The LFS gets them in regularly, and out of 6 none of them have had black on the pelvic fins. I Googled "Yasha Goby pair" and noticed that most pairs seem to have one with black one without, but not all pairs. Albeit, just because it is a picture of two Yashas, doesn't mean they are really a breeding pair.

That's funny. My guys are totally able to specify whatever I want and the wholesaler tries to accommodate. Every once in a while they cannot, but more often than not it's exactly what I specify. They got a pair of harlequin filefish right on the first try. I just showed them pictures of the males vs. females. On the other hand, they aren't the cheapest wholesaler, but they really are worth it. I can try to get you the name if you'd like. I used to know it, but oldness and name retention don't mix well. You should see them at parties. It's never pretty. Of course, you are in Canada, so it comes down to whether they can ship to you, but it doesn't hurt to ask, right? The male was back in the rocks yesterday afternoon and I think I witnessed part of the spawning (male/female switching who was in the hole in the rocks over and over) at about 1:30 pm yesterday (8/19/12 for anyone keeping count). I haven't been down there yet today but I'll report if there's news.

If you remember the name, yes please PM. There are only so many wholesalers... (Sorry I'm messing up your journal with off-topic stuff) Isn't it frustrating when you can't see the possible nest site very well? Drives me nuts. Maybe there is some sort of small camera on a cord we could use or something.

Sorry. I really got buried in work and look to be the same until at least the weekend. I believe Quality Marine are the people I dealt with (through the LFS). Not the cheapest, but I've been quite happy with the fish I've gotten from them. I don't know what to think about my male. He spends most of the time in the hole but then he'll be off hanging with the female again. No clue and I may have been premature to get excited.

For whatever meaning it may hold: Today, 30 Aug. 2012, the male is again out and around the tank. 11 days since the last one. Bandeng's experience was 8 days between hatches but 5 days of incubation, suggesting there are a few days after hatch and before the next spawn:

I guess I need to hit the fish room early in the morning in 11 days and see what there is to see. Okay, back to work. Only 2-3 more projects to get done before Tuesday.

Nice to know Andy. Thanks for sharing this info! Could come in handy for someone also working on this species.

Thanks, Adam! Just finished my last project after working 'til midnight last night. That means I actually get the long weekend. Woohoo! The male is back under the rocks today. It's definitely a pattern now, IMO. Now to figure out what it means....

So, the male and female were interacting a bit yesterday. Maybe the spawn day? It would make sense if it's a 5-6 day incubation. Eleven days from the boy hitting the rocks would be about 9/10 or 9/11.

Hmm, that is interesting Andy - I've noticed similar behavior that you're reporting. I'm just wondering if I'm over looking eggs in the donuts I made for them to nest in.

Quite possibly, especially if they tend to hatch at weird times.

Well hopefully I'll have some more Stono's to compare to. Just got in (well going to pick up at the airport in an hour lol) 7 Dracula's. It will be nice to see if they follow a similar pattern as the yasha's. I will note tho that my yasha's do not have the black on the fin - yet they are constantly next to each other, even if one goes out for a swim, the other is next to them. Definite size difference, but unless I'm totally blind (which is possible), there is no black on the fins. They are in a 20L all by themselves, with about 1/2" of sand/crushed coral base. The donuts are just there to make egg collection easier. Keep up with em - I know I've missed Helfrichi eggs because I thought no egg could be as small as they are!

i have brought a pair of yashas now, it might be worth noting one of the pairs in the shop only just had the black on the fin, it litrally was just on the tip of the fin, but was there i picked the pair with more black just to be sure!!

Good luck with those Dracs. I'd like to head that way, too, if I wind up with any success with these. And good luck with your new Yashas, Matt. If my math is correct then it's possible there will be larvae in the morning! We'll see. And hopefully tomorrow won't be as ugly busy with work as today was.

Oh, as an aside, I found a small clown that's been living in a brute trashcan for months and I tranferred it to the Yasha tank to serve as a dither fish. The female immediately came out to display at the clown quite aggressively to protect the rock work. Pretty cool to watch. Then the next day, the goby was right back to normal--hiding under the rocks all day.

My yasha's just hide hide hide! Always together tho. I'd worry that they weren't eating but they destroyed 100 live mysid shrimp in about two days. Andy are you checking for eggs? Or just going after larva? Quick shot of half the Drac's and some Helfrichi's in QT Sorry for huge size - forgot I had camera on max

Mine are mostly in the rock work but rarely come out, like the female displaying at the clown (first time she's been out), or the male with his "off" days. I watched them for about an hour today. Both male and female occasionally came to the entrance of their cave to be aggressive toward me. I find that encouraging, BTW.No luck on any larvae today, but I might have missed them. I had to take the kiddo to school and some lights in the room had already come on when we left. The male wasn't out-and-about yet today, though. Could be the clownfish. Could be some other reason. No clue. I'm not directly checking for eggs because the male spends his time in a hole in the very bottom of their rock work. I'd have to dismantle the whole tank to get to it. Nice photo! Good luck with them!

Well it is pretty dang easy to pair these guys. Males have a long pointed pelvic fin, where females are more rounded. So by that, I've got one male and three, possibly four females. I'll take pics tomorrow. Now I've got to pull them out of the QT tank they are in now and get them into a broodstock tank. The male is already sharing a shell with another drac. Lots of food and 12hr light cycle and we'll see

Looks like I must've lost the male. At first I thought they just moved his hiding place, but I haven't seen him in an awfully long time.
