I thought you were meaning a 30cm long pipette with a golf-ball sized bulb.Guess yours is pencil sized with a bulb like a pacifier´s mouthpiece,a Pasteur pipette.
Yup, the tiny ones. They hold like 3 ML?
Until I see some eggs,I can´t call it a spawn.I imagined mandarins would need a tall tank for their spawning rise,like pigmy angels or seahorses and so their 10g should be totally unsuitable.But I see that they join at the surface and then start doing their thing there,so I don´t know,must wait and see!.
Well, we have a bunch of info and conflicting observations regarding the required spawning "height" necessary. Observations in the wild suggest that they don't go even "close" to the surface, only rising maybe 18" or so - at least that's what's published in the current issue of Coral Magazine regarding their spawning behavior at YAP.
In MY tank, there's maybe 16" of vertical height and yet my pair NEVER utilizes the whole height of the tank...instead they typically start 4-8" below the surface, hit the surface, "scoot" across the surface and then release the eggs in a splash.
Contary to what I've been able to record and show in my pair of Mandarins, W. Mai suggests that in his S. picturatus, if they make it to the surface PRIOR to releasing gametes, there won't be a release on that particular rise. To call that observation solid fact and suggest it is applicable to all Synchiropus would be assuming way too much, especially considering my pair.
Someone else posted somewhere on this thread (or maybe my Red Scooter Blenny Thread) that they had a pair of Red Scooter Blennies (Synchiropus stellatus) spawning in a 10 gallon tank. So why wouldn't it work for you? Maybe it's up to the particular pair's preferences?
Of course, you could always go find a 15 gallon X High in place of the 10!
Turn those pumps off and watch them like a hawk...sometimes they rise for 2 hours before spawning! I can only recall a few times where I had rising activity that DIDN'T culminate in a spawn. When they stop rising and go to sleep, I bet there are a few eggs, somewhere at the surface!
Regarding ammonia,I have seen larvae of several species tolerate rather high levels of it.Surprising:eek1:
Yeah, but I've been having some heavier losses in the GBG larvae over the last few days, at least it "looks" that way, and Ammonia is the only thing I can safely say is out of whack (and do something about!)
FWIW,
