Breeding Journal, Species: Chrysiptera parasema

Breeding Journal DataSheet General Species: Chrysiptera parasema, Yellow-Tailed Blue Damsel. Social Structure: Pair. There was a third, but that one was smaller and weaker and never thrived. It perished after about a month in the reef tank. Size of Individuals: Female 1.25" and male 1.5" TL. Age of Individuals: Unknown, bought as large juveniles. Date added to Tank: March or April 2012. Broodstock Tank Details Size of Tank: 90-gallon SPS dedicated reef tank. Substrate Details: Just live rock, no sand. Filtration Details: SWC 180 Cone, filter sock for 12 hours after waterchanges. Water Changes: 10 gallons weekly, 50 gallons 4x per year. Water Temperature: 80-84F Lighting: 2x250w halides, 2x54w T5 Lighting Cycle: T5s run for 12 hours, halides run for 7 hours. Other Tank Inhabitants: Pair of Tomato Clowns, Hawaiian Flame Angelfish, male Sqarespot Anthias, Tailspot Blenny, Yellow Coris Wrasse. Many inverts. Broodstock Feeding Details Food Types: Homemade frozen mash, PE Mysis, TDO EP1. Frozen and pellets fed 50/50. Feeding Schedule: Once per day. Spawning Details Date of First Spawn: Possibly as early as fall 2012. Territorial breeding behaviors observed, but eggs not found. I was away from the tanks for weeks on end, so I may have missed the spawns. Spawn Time of Day: Varied - usually morning or early afternoon. Dates of Consecutive Spawns: Feb 13, 2013? First eggs found evening of Feb 14, 2013. Around 24 hours old?...will revisit this estimate. Mid-March. 01/01/14. 01/19/14. Courtship Details: Early observations: I've been away from the tanks for weeks on end, but noticed the Damsels were guarding a cave in a rock under an Acropora coral back in October 2012. They chased other fish away, and bit my hand if I came near the cave. They displayed this same behavior at Christmas 2012, but I didn't find any eggs. Later observations: The male would try to entice the female towards the cave by swimming up to her, displaying, and swimming slowly back towards the cave. He would repeat this until the female would follow him back to the cave. They would do this many times before the actual spawning event occurred. Egg Size: Approx 1.5 mm by 2-3 mm. Egg Color: Clear, greyish tint at first. Later, eyes are clearly visible and appear shiny. Egg Count: Several hundred, likely pushing a thousand. Hatch Details Hatch Date: Feb 18, 2013 Hatch Time of Day: Night # Days after Spawn: 5 Larvae Description: To the naked eye they are difficult to see, quite clear with two black eyes when viewed from above. Viewing from the side reveals bright blue eyes. Fully developed mouth. Can't comment on gut and cloaca...I'm not learned on that yet! Measured at 3.6 mm TL. Consecutive Hatch Dates: 03/20/13. Larvae not retained, no food cultures at the time. 01/05/14. Not collected. 01/23/14. Larvae collected. Larval Tank Details Temperature: 80 Size of Larval Tank: 9-gallon BRT Substrate Details: None Other Tank Decor: Airstone, heater Filtration Details: None Lighting: Little dim LED light. Lighting Cycle: 14 on, 10 off. Water Changes: TBD. Larval Feeding Details Food Types: Rotifers "L" type. Will need to confirm the larvae's ability to eat these. [EDIT: The larvae did not consume these rotifers.] Feeding Schedule: Continuous. 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 Feb 15, 2013. I will be away from the tanks for another month or so. I plan to start collecting the larvae after that. I think raising these damsels will be good practice for more challenging species, and will allow a greater array of species to offer to my buyers.

Feb 15, 2013. 7:30 pm. Here are some (not very good) full-body photos of the broodstock: You can see the male up on the left of the photo and the blue blur near the middle bottom of the photo is the female:

I think Andy Rhyne is looking for broodstock of this species...

Kathy, in this lone experience, they were incredibly easy to pair up. I don't think Andy would have to wait long for a breeding pair if a small group is purchased. I'm home for the next couple days, and if they hatch while I am home I will collect with Chad's larval snagger. I have no hope of raising them right now, but if possible I will take pics and post them up. I need to do lots of research on this species. It is the most challenging species that I have breeding right now so it will be a good experience.

Feb 18, 2013. 10:30 am. I think they are getting close to hatch. Maybe tonight? I hope so because tomorrow morning I go back up to camp (work). However, for the life of me I can't find my snagger!

Well, they hatched lastnight (Feb 18th)! I couldn't find my snagger anywhere, so I put a filter sock on the drains and hoped to catch a few live ones this morning...and I did! I think the eggs were close to 24 hours old when I found them on the evening of the 14th. My first photos in this journal are from the evening of the 15th. So I believe they were laid on the 13th which would make the eggs hatching on the evening of the 6th night (give or take a day). Sorry my photos are terrible, I just have a USB microscope that takes very small file photos. However, the USB microscope does allow me to enter the magnification and then measure the specimen accurately. They look fully developed and ready to eat to me, yes? Given the mouth size, I believe rotifers will be small enough (although maybe not nutritionally rich enough), although I've been known to convert microns to mm very poorly. Haha! Rotifers are approx 120 microns by 180 microns if I remember correctly, which is 0.12 x 0.18 mm, right? Feb 19, 2013. 8:30 am. Could be 1-10 hours post hatch depending exactly what time they hatched.

Thanks Darren! So, you think rotifers will fit in their mouth then? If so, I will try enriched rotifers first. Even though I know a person doesn't need to enrich rotifers grown with RotiGrow Plus, I have become proficient at enriching them with N-Rich PL Plus and keeping a supply of well enriched rotifers available to fry. I do plan to get a culture of Apocyclops panamensis going in the spring, but it could be some time before I am able practiced enough to produce a stable culture.

These fish are either not very prolific, or they changed spawning locations. I've seen the bigger one hanging out on the back side of the same rock, but so far I have not seen any spawns in that cave. I will be ready to work with these mid-May. I'm trying to source S-type rotifers, and have my LFS looking for some copepod cultures...

Well, I've been ready to work with these guys since mid-May, but I haven't seen any eggs since February.

I finally found some eggs lastnight! They hatched lastnight, but I didn't collect them. Now I know where they are, I will grab the next batch.

Well, I didn't see another batch until January 1st. This batch hatched on January 5th. I couldn't collect that day. I'm really hoping to get started on these guys soon, but they haven't been very prolific.

Ok, I found a spawn on Jan 19th. They should hatch tomorrow night, but I'm going to set up the snagger tonight just in case. I only have "L" type rotifers, but maybe they are small enough.

Thanks Shannon! Fingers crossed... No hatch lastnight - didn't expect it. Got my snagger in there again tonight. I'm kinda hoping they don't hatch tonight because I have to work an extra early shift tomorrow, but they should.
