Damn. Three pages back. Shame on me. Photo of the night: I've finally come up with a possible first food for these buggers and I'm finally starting feeding trials. I have a cyclopoid copepod (Apocyclops, maybe) that breeds readily to densities far greater than possible with A. tonsa and really, really quickly. I have them in what sure seem to be sustainable cultures using Oxyrrhis marina (a heterotrophic dinoflagellate) as food for the copepods. O. marina are also really easy to culture (I do them in open top jars like my rots) using algae paste as a food for the flagellate. So, here's a copepod in culture that's being grown with _no_ live phytoplankton. Cool stuff. Now we just have to see if the fishies will eat them, but Apocyclops have been used successfully to rear fish and crustaceans, so I'm hopeful.

Hmm, looks like zero hatch rate on the eggs despite a good number of them developing as above. Maybe the O. marina went after the eggs (I've seen them attached to detritus like dead rots and such). I think I need a hatching vessel inside the larval tank.

I'll need to know more about that copepod at some point LOL

They don't breed as fast as rots, but they are still awfully darn fast. I started out with them on June 22. It was a dense culture, but still only about a quart, yeah? I'm up to about ten gallons of them now and dense, dense cultures. It seems like their development rate from hatch to adulthood is really, really quick so cultures get a good exponential curve going really fast. The video is of my food trial container and I started it with just a quick swipe of a 54 micron mesh sieve through the 5 gal. culture. It's about a gallon and they have filled it up. Andy Rhyne says that the genus has been used for fish aquaculture and I found a paper on using them for crustaceans. Fingers crossed. Now I just need some larvae to hatch. I'm back to bacterial problems despite the peroxide bath. The copepod and O. marina water is probably loaded with bacteria. So, I'm trying a hatching container (a small deli container turned into a downweller with a 1 micron mesh bottom) in the feeding chamber. So, same water but the mesh should keep some of the baddies out. If they hatch then I can turn the larvae loose. 117 eggs today.

Do you have any info on the difference between males and females, coloration-wise? I read that they are protogynous hermaphrodites... Is there a distinct difference between M and F as far as color, or just size?

I have seen no obvious differences on these two (who are still alive and spawning) other than size, with the female being much smaller than the male. The female also gets enormous when she's hydrating eggs, but that's not a normal thing.

Good to know. I was looking in Thresher's book for the info. I need to try a pelagic species.

Bringing this back from the depths of 2010! Andy, when you paired these guys up - was it random or were they picked up as a pair? Broodstock seems like they would be easy to find (as well as not to expensive!). Thanks so much - I've really enjoyed going over your reports and pics!

I put them together with a little help from the wholesaler. I had the LFS guy ask for the largest and smallest 6lines they had. It worked really well. I did start out with one large and two small but one of the small ones kept ending up in the overflow. I figured that was a sign to get it out of there.

One last question (lol I know I'll ask more Were they spawning right before lights out or right after? I'm trying to get my timing down for turning pumps off so I can collect in order! Thanks much Andy!

They were (and are, I think) spawning about an hour before lights-out.

Thanks Andy - funny seems like it always ends up with the quick release then they get away from each other as fast as possible! Guess that makes sense, probably the most vulnerable time for the fish. Thanks again, looks like my female is getting chubby, I'll have to watch for it tomorrow! Cheers!
