Breeding Journal DataSheet This first post should be updated regularly to include new information as events take place or changes are made to your system General Species: Centropyge bispinosa Social Structure: we shall see..... Size of Individuals: male approx 3.5", female 2.75" ( second female 2", added 9/26/15) Age of Individuals: Unknown. Just purchased the female today, have had the male for > 1 year in the display tank. Date added to Tank: female in QT tank as of today. Male probably added early 2012 or late 2011. Broodstock Tank Details Size of Tank: 125 gallon mixed reef tank. Substrate Details: aragonite Filtration Details: 75 gallon sump with skimmer, GAC, GFO, lots of live rock (typical reef setup) Water Changes: 25% monthly with Reef Crystals Water Temperature: 79 degrees F Lighting: LED mixed blue and white Lighting Cycle: blue on 0900, white on 1000, white off 2130, blue off 2230 Other Tank Inhabitants: yellow tang, pair of perculas, scooter blenny, 2 Barlett anthias, 3 chromis, cleaner shrimp, several peppermint shrimp, and other inverts I am forgetting at present... Broodstock Feeding Details Food Types: Variety of frozen (mysis, brine, krill, omnivore), nori several times a week, Ocean Nutrition flakes, pellets. There is tons of grazing to be had on the reef (sponges, algae (unfortunately), tube worms, etc. I have seen the male occassionally take a nip off a coral (most of my colonies are large and well established), but have never seen anything that appears damaged by him. I know this has been a concern with other reefers. Feeding Schedule: dry food on timer with small snack twice daily (midmorning and mid afternoon). Frozen fed early evening (1800-1900). Spawning Details Date of First Spawn: 11/24/13 Spawn Time of Day: Approx 5-10 minutes before lights out Dates of Consecutive Spawns: They go about there spawning routine almost every night that I am around at that time. Courtship Details: About a half hour before lights out, the male usually begins with swimming around the tank and displaying in the center of the tank. The female often ignores this for a long time and just grazes around the tank. SHortly before lights out she will then begin following him up to the middle of the tank (they seem to like the area right under the return nozzles). Lots of nuzzling and nipping by the male, and then the female darts off releasing eggs. I have yet to see a sudden rise & release that I have read others report. Egg Size: 700 micron spheres Egg Color: Silvery/translucent, with central oil droplet Egg Count: Appears to be several hundred Hatch Details Hatch Date: First hatch on 4/2/15 Hatch Time of Day: Approx 4pm (16-18 hrs post spawn) pro larvae are found # Days after Spawn: 16-18 hrs post spawn Larvae Description: Silvery 2mm pro larvae with speckled dorsal stripe. To the naked eye appear as very thin 2mm grey line in water that occasionally "twitches" Consecutive Hatch Dates: 4/3/15 Larval Tank Details Temperature: 79 degrees F Size of Larval Tank: Small round 4x4x3" clear plastic container Substrate Details: None Other Tank Decor: None Filtration Details: Rigid airline with very slow bubble rate Lighting: Frag tank light (led 50w) on 9a-9p, then 13w cfl indirect on overnight Lighting Cycle: As above Water Changes: None thus far Larval Feeding Details Food Types: Plan to add parvocalanus and t-iso Feeding Schedule: Metamorphosis/Settlement Date of Settlement Start: Days after Hatch: Date of Settlement End: Description of Fry: Grow-Out Tank Details Temperature: Size of Grow-Out Tank: Substrate Details: Other Tank Decor: Filtration Details: Lighting: Lighting Cycle: Water Changes: Size at Transfer: Age at Transfer: Grow-Out Feeding Details Food Types: Feeding Schedule: Additional Information (No Pictures or Videos in the Section Please) Miscellaneous Information: You will be required to provide photographic or video evidence in this thread of each event submitted for the MBI Program. If your thread does not contain these photos the MBI Committee will not be able to approve your reports. PHOTOS AND VIDEO S MUST BE PLACED IN ADDITIONAL POSTS, NEVER IN THE FIRST POST IN A JOURNAL.

I have always wanted to try breeding a dwarf angel, and finally found a suitable size female (hopefully) today. She is in QT for now, hopefully will eat good, and be introduced to the main tank with the other in about a month. The female was hard to get a picture of today, very shy, hiding in the back of the QT. Hopefully I'll update this journal with good news in a month or so. I know it's a very long shot for anything close to success, but what the heck! Just wanted to get it started... Male (my Regal tang always tries to hog the pictures!) Female

Well, bummer.... First setback. Came home from work to find my new coral beauty dead in the QT. I noticed that she seemed to have a lip infection day before yesterday, gave a dip in metronidazole yesterday. She was eating good up till these symptoms developed. Back to the drawi board, trying to find another possible mate.

To my knowledge, with dwarf angels it's all about size. The smaller, younger specimens are female, and can become males as they grow larger/older. In a small harem of 3 that are all same size & age, one will become dominant and transform to male, growing larger. This is opposite from clownfish. Anyone with any more accurate or specific info, please chime in! Btw- I'm still trying to find a healthy young/small female locally. It's been harder than I thought!

Finally got another one through QT. This one in about 2cm smaller than my male, Got it from a friend who couldn't keep it (his Darwin clowns were constantly after it). So far no aggression between the two. I've seen my male displaying, flaring his fins, sometimes in the evening near lights out. Nothing more than that. They have been together now about 10 days. We'll see what happens. Hopefully I don't have 2 males! Not a great picture, but hard to get them both in one shot without movement!

I have two of C. bispinosa in my tank (90x45x45cm) for ten months. I have been getting the eggs from the tank for almost four months everyday. I collect them with the net set in the over-flow tank set beside the main tank. The number I collect count from 200 to 1400 eggs per day. Unfortunately, however, I never had eggs fertilized. Could anyone suggest how to improve the condition? I used to get the fertilized eggs of C. ferrugata a few years ago almost every night for two years. Sabahi (Bandeng in MOFIB)

I have read that exposing centropyge eggs to air can harden the shells and kill them, so maybe your collection technique is killing them. Try to keep the eggs under water all the time.

If mine ever do spawn, I hope to devise something to accumulate the eggs at the surface before going down the overflow. I suspect that rough ride would probably be detrimental to the health of eggs.

Thank you for the comments. I once tried to collect the eggs from the surface of the spawning tank but they were not fertilized at all. Sabahi

Saw some encouraging activity this evening after the lights dimmed. The pair were hanging out near the surface with the male kind of nuzzling the female's ventral area. They would then swim away around the tank separately for a minute or so, then repay this behavior. I never saw anything that looked like true spawning. I'll try to get a video next time.

It looks to me like you are close to a spawning. They do a lot of muzzling and chasing, then in a split second they rush to the surface. It happens pretty fast, in about the last 5 minutes of daylight. I dont know if you have light dimming but somehow they are pretty good at keeping time if you don't.

I caught a video of my coral beauties spawning last night, the first time I ever witnessed this. Right near the end of the video you can see the female release a cluster of eggs, and one of the chromis immediately go after it. The video is dark because only the actinics are on, very near lights out http://youtu.be/D1Q9NfwgvDo

Nice video. The male behavior of nuzzling and nipping is classic, but the pair did not have the typical spawning rush, and I couldn't see very well the number of eggs released but it is usually in the hundreds, right on the surface of the water. Maybe your pair is relatively young, I think soon you will see them spawn regularly.

Now to figure out how to collect eggs, and see if they are fertile. I might try turning off my main return pump to see if I can keep them from going down the overflow. Hopefully the chromis & anthias will leave me some!

Collecting isn't easy, everything in the tank gobbles up the free caviar as fast as possible. My shrimp used to hang upside down at the overflow and urgently grab every egg. One way to harvest is to turn the lights out quickly so the fish will not be able to eat the eggs, then use a larval/egg snagger which skims the water surface into a container while a powerhead pumps water out of the bottom of the container to create a flow.

Another failed attempt to collect eggs last night..... I staked myself out in front of the tank near lights out, and watched the pair go through their usual chase around the tank for about 15 minutes. Then as usual they stopped just under the return nozzles for the actual spawn. As soon as the eggs were released, the chromis and anthias were on them in less than 1 second. By the time i went into the fish room (less than 30 seconds after the egg release) and looked around in the water and on the surface, I couldn't find any remaining. This is definitely going to be more of a challenge than I initially thought! Now I can see why my efforts to collect some eggs in the overflow haven't yielded any - none are getting the chance to make it into the overflow box

I don't know that you have an easy solution. You could stand in front of the tank until they spawned with one hand on a switch that would kill every source of light in the room. I don't think the anthias and chromis will forage in complete darkness. Or you could remove either the angels or the chromis/anthias to another tank. Neither one is an easy choice. And even if you removed the fish eating eggs, the way would be clear for your shrimp to come to the surface and take their place. Sorry, I wish I could help you with a better solution.
