I will certainly do my best!!! The new moon is this weekend and Fabio has started doing his dance for Faith again in the evenings. She hasn't looked hydrated at all yet but I'm checking for eggs every night.
Those interrupta in your photos have awesome color. Just lovely!
Do you still have your latz?

I sold the pair of Latz to a local reefer in the Bay Area when I took down my tank. I'm sure they are doing great as he is a knowledgeable reefer. The color on the pair of interruptus from Frank B. were incredible. When I received the fish, they were under an inch long and I was scared that they were too small and wouldn't make it. Boy was I wrong as they started to eat immediately and thrived in my tank. The male took on an intense blue coloration and really looked like a super male in no time. I always said that my biggest mistake in reefing was letting go of those fish and I still believe it today. I will not make that mistake twice.:)
 
Hi Karen,
How important would you say wild caught plancton is to your operation? Im assuming very but would love to hear your thoughts on the subject. How close are we to having enough live feeds available to pull off breeding operations without wild caught feeds? Im not a breeder but I do like to browse the aquaculture websites on occasion and while I have no idea what half of the products are I have noticed theres quite a bit of different feeds and supplements available these days. As always, whatever you feel comfortable sharing is interesting to me, love all your updates on the blog and always looking forward to new ones. How are the Venustus doing?
 
We seem to have a trend going this week with the spawning or lack there of. We have the interrupta and flameback angels close to spawning with this project and I have potters angels and flame wrasse pairs/harems with another project. All of the males are doing a spawning dance and the females are watching them and seem to be thinking that the guys are just being silly! Although I am frustrated at the lack of fertile eggs it's pretty funny to watch. Thank goodness the venustas are spawning so I can keep moving forward.

The venusta larvae show a behavior I have not had experience with previously. They like to sit on the bottom which makes it difficult for me to keep the larval tank clean. They were doing great but as "stuff" accumulated on the bottom it became a messy environment for them with water quality suffering and I lost the batch. I have made some changes to the larval tank in an effort to keep them off the bottom and there is a short update on the blog. I just finished collecting another batch of eggs so hopefully these are fertile and we can try again.

In regard to live feeds, my goal is to get to where larval runs are successful with only cultured foods so that larval fish can be reared anywhere. I used only cultured foods when I raised the G. personatus and had a very large tank with flow through water to use which helped with water quality. I think that wild plankton is the best chance for success initially when raising larvae on a smaller scale although it can contain undesirables. I can raise enough cultured foods currently if every culture comes up as planned (and most aquaculture facilities can raise more than enough) but I feel that the cultured copepods don't have the nutritional value that wild plankton has. In general we always feed the same microalgae species to the cultured foods. I use 5 different algae species but that is still nothing compared to the variety of food items in the ocean that wild plankton is consuming. There are all sorts of good enrichment products available but they often result in bacterial blooms within the larval tank which can be fatal to fragile larvae like the smaller angelfish species.

When using only cultured food items the transition from one size of food item to the next can be tricky whereas the wild plankton can be size sorted and offer more variety that the larval fish will find attractive as prey and catchable.

With the G watanabei late last year and with the interrupta and venusta larvae I am using a mix of cultured and wild plankton and hope to steer the protocol more and more towards only the cultured foods.
 
Hi Karen,
wanted to ask this question for long....
how the egg are caught(not the egg screen you described)...?..do you look to the the pair's activity and scoop out the water the moment they spawn..or something along the line..?
 
Quick question: How are the G. Watanabei that you raised? Also, have any wrasses been successfully raised in captivity? Good luck with this batch of Venustus and hopefully the others get going soon!
 
Paka -- any pictures or blog links of the Potter's Angel pair? Very curious to see the color differentiation (if there is one) b/w male/female. Could you explain the pairing process with this particular species?

I normally check to see if the female is hydrating (ovaries hydrate and become larger before the female spawns causing the female to look more plump than usual). You can usually see a difference in the morning and the "plumpness" increases through the day until spawning time. In some individuals the plumpness doesn't show up much and in others they look like they're gonna pop! So it's good to get an idea of how the females normally look both before and after eating and what "hydrated" looks like compared to normal.

Most of my pairs spawn within a couple of hours after lights out (the G. watanabei spawn about an hour before). So I turn off the pumps to the tanks that might have spawners about a half hour before lights out. If I can stay awake I collect eggs around 10:30 or 11:00. If I can't stay awake I set the alarm clock for midnight and collect the spawns then.

I'm glad you asked about the G. watanabei since I just realized that I missed the first birthday which was Sept. 10! I have one here that is doing great. She had some buoyancy issues like the others when she was young but has outgrown them now and is fine. She's waiting to go to her new home with Copps when he gets his tank done.

I don't think any ornamental wrasses have been successfully raised in captivity yet but I'm not 100% sure of that. There are lots of individuals working on hatchery methods for marine ornamentals that we just don't hear about.

Sorry I don't have any photos of them. I'm not much of a photographer and just have a simple point and shoot camera. The fish are always blurred when I take their photo. I may be able to get some video though. I haven't noticed any difference in colors or marking between male and female. I have two pairs and in one pair the color is darker and in the other pair they are both washed out looking. To pair Potters I just put a smaller fish with a larger fish and they usually get along. I have tried trios in the past and always end up having to rescue one of them several months into it and just settle for the resulting pair.

Is that the best method of pairing for most angels?
 
After reading through rct website usually combining 2, one slightly large with result in m/f I plan on doing that withy flameback and potters soon.
 
Congrats on what has been done so far.

tank breed interrupta's color was not as good as wild

Does this apply more to this species, or to fish in general?

Also, is the kickstarter is still floating?
