On 1/25/2014, he once again began refusing food. On day 15, I realized he may make it this time, so I scrambled to get a breeding net ready and BBS hatcheries set up. At 5pm on 2/12/2014 (day 19), I started the first brine shrimp hatchery. At 5pm on 2/13/2014 (Day 20), I noted that the first BBS hatch was successful, started a second, and moved the male in to the breeding net. On 2/18/2014 (Day 25), 4 babies were released. On the morning of 2/19/2014 (Day 26), the remaining 36 were released. Over the 2 day release, 40 live fry in total were collected and moved to growout. Upon cleaning the breeders net, 1 dead fry was found.

36 babies were released this morning around 10:30 am for a total of 40 settled fish. I additionally found 1 dead in the bottom of the breeder net after removing the living ones.

Looking good! Now to just keep them well fed. Cool to see how they like to hide in plant. In the wild, some schools of these live in eel grasses, even though we always see pics of them on reefs and in anemones.

2 DPS update: I was a little conserned yesterday as it seemed that only a few of the babies would move from their spot at feeding time to chase food. Most would stay in their safe spot, and just grab food that came right to them in the current. Today's feedings are much better, as at least half of them are darting around chasing the food... Much more of the feeding frenzy I was expecting. Feeding Frenzy.

Thanks! I am trying to feed them 5-6 times a day with BBS that is no more than 24 hours old. The feeding will be less frequently for 3 days next week while I am on my business trip, so I hope that doesn't cause any problems. I have asked my wife to try and feed them at least 3 times a day. I find it very interesting that about 1/3 of them love hanging in one of the plants, while the others don't go near the plants at all.

10 DPS update: No losses noticed, but I have been unable to count them. When not feeding, they move around the tank in a baseball sized school.

Today (18 dps), I moved clutch 1 into a 15g bow front that was given to me. I carefully counted as I transferred, and there was indeed still 40 fish. One of them got very traumatized by the move and was floating on his side on the surface for a few minutes, but now 30 minutes later he must be OK and back swimming in the school because I can't pick him out from the rest. The move was necessary because (1) 40 growing fish were going to quickly outgrow the 5g, and (2) the male has been carrying clutch 2 now for 16 days so I needed to start getting the 5g ready for them.
Hopefully I can utilize enough of the misc used equipment I have laying around to keep things going until Petco has another $1/g sale. At that point I will start building a proper grow-out setup.

They look great in the above photo. They are prone to "sudden fright " with certain events, such as transfers, water changes, etc. I have also had this happen, and they will recover if not overly traumatized. The first time I ever witnessed it, though, I thought I had killed the fish and almost disposed it! Fortunately I had a few chores to do, and when I cameback to remove the corpse, it was happily swimming around again. Sounds like your pair is going to be productive! Soon you'll have tanks all over. Congrats on the good work!

Thanks Ken, good to know! I currently have 5 tanks in service and the 5g is now clean and ready to come on line for clutch 2. I also have a 20g that could be brought on line quickly if needed, but having one off tanks spread around the house is going to quickly become a pain. Hopefully I can set up a consolidated grow out rack soon.

Clutch 2 is at 20 days held so far, so I moved papa back in to the breeding net.

It is day 25 for clutch 2 and no releases yet. As I was concerned with being sure I could feed the male for a while before putting him back with the female, and also wanting to eliminate the work involved with fry transfer that i had on clutch 1, I am trying something different. I divided the 5g tank in 2 with egg crate, placing a fake plant on one side and the male on the other. My hope is that when he releases the fry, they will go through the egg crate to the cover of the plant and away from hungry dad. This will theoretically allow me to feed the male for a few weeks in the same tank as the fry. I don't know if it will work, but it is worth a try. I am slowly gathering pieces to build a rack that will house several 10g tanks to make all this easier. It would definitely accelerate my efforts if Petco would have another $1/gallon sale.

Well at least 17 fish from Clutch 2 have been released so far and he is still holding more. It has been a frustrating morning though, as my divider idea is not working well and the fry do not look nearly as developed as the first clutch.

The total count for the Day 26 release of clutch 2 was 19, but more are expected tomorrow. They are clearly less developed than those from the first clutch, with 15 of them spending most of the day huddled in one of 2 packs in corners of the tank. The other 4 have found cover swimming in the plastic plant.

The rest of clutch 2 was released today (day 27, 23 released) for a total clutch size of 42. One appears to be DOA, so there are currently 41 free swimming from Clutch 2.

Clutch 1 (36 dps) has been on exclusively frozen food for 5 days now (frozen SF bay BBS and Cyclop-eeze). More of them become interested in eating it at each feeding. The addition of a nano power head to the tank helps a lot. I removed 1 dead one today that looked like he hadn't been eating, so we are now at 39.
Clutch 2 (7 dps) is doing good on live BBS. no losses so there are 41 from the clutch.
The Male has been separated from the female for feeding for the last week. It is a painstaking process, as he has never been a fan of dead food. It isn't a problem in a tank with other fish because he doesn't take the time to look at what he is about to eat given the competition. Alone, he looks at it and then moves on. I have taken to feeding him by coaxing him to the surface and then adding a single PE Mysis via a dropper. When it is released within about 4" of him, there is about a 50% chance he takes it. I will do this until I have seen him actually eat 3 or 4. I am doing this several times a day. I have tried to find live food to power feed him with but no one around me sells live mysis or blood worms.
