Well..... The babies are really interesting. I've moved them onto a centralized filtration system... sort of.... I'm currently keeping them in a 10g tank that's using the parent tank's sump in a sort of mini centralized fashion. They are doing great. Haven't lost one in weeks. It's really interesting to me how they grow though. At first they grew more like little orange worms, than actual fish. Even though I could definatly see that they were clowns right after meta, they were about .5" long, but very slender. In the past weeks, they have grown only slighly longer, but they have increased their mass about three fold. They have widened from top to bottom, and their fins have gotten much longer and more robust. I would liken it to the difference between a 2" clown and a 3" one. Their striping has seemed to stop, and they look like a bunch of extreme mis-bars. Not sure if/when the striping will crank up again, but live and learn. All in all I'd say they are doing great. Sorry no pics tonight as the lights are already off, but I'll try and post a video tommorow. Hopefully if I get done with work early enough, I'll be able to get some good footage of the babies as well as the new WC PNG percs I picked up recently from a local hobbyist. They are sweet, and have already breed in his aquarium, so fingers crossed. If they like their new home, I should have a new project soon.
As for the other hatches. 100% mortality on all so far, but, I spent presidents day (one of the few I actually get off) re-reading a book on breeding, and I'm very encourage that I've figured out what I've been doing wrong. Apparently the enrichment feed for the rotifers is very oily, and that can have drastically bad affects. A slick will form on the surface which itself can kill the fish, but also cuts off the O2. Also the way I was lighting the tank seems to be an issue. Apparently 14 or so hours of dim/dispered overhead light is the key. Lighting the side of the tank can cause dis-orientation and make feeding difficult. Also I was leaving a small lamp on the floor at night, so they were being side lit all night long. According to the book, when the lights go out, the larvae settle in for the evening and don't feed or expend much energy. Rest if you will. So keeping that lamp on at floor level, which was causing the side of the white bucket I've been rearing them in to glow, was probably a huge issue. They've got a nest right now which will hatch Sunday most likely, but I'm going to let this one go. My plan is to build a proper larvae rearing set-up next week. I also installed an auto feeder on the parent tank, so now they're getting fed at least 4 times daily. I think this will make the next batch much hardier.
All in all, I'd say that I got very lucky with the first batch, and despite the hundreds of hours of reading/experimentation, I kind of found myself in a "can't see the forest for the trees" kind of situation. Their is so much information that it can become overwhelming, but re-reading the book has brought me back down to earth. I think the next batch I try will be straight up by the book. I've already got all the equipment I need - except that I'm looking for somewhere to buy black marine epoxt paint for the inside of the bucket - which I will hopefully find soon, so now it's just a matter of actually doing it.
How bout you? Are they laying agian???? How are your babies??
