Well, I promised to give updates on the first hatch...so no matter how dismal, I lost two today. I moved them to my shelving unit that will become the rearing station. I just drained most of the water, cleaned the sides, and carried the tank. I filled it up about 50% with their old water, and took advantage of the situation and added 50% water from the parents tank (directly after a large water change in the parent tank...stupid).
The pH went from 7.9 to 8.2 rather quickly, so I assume this was the problem. All the rest are happy and eating well. So make my count 7 now...at this rate, I'll be lucky to get any to a pet store!
The other hatch is doing very well, only lost 3 that i can see today, check the other thread for an update. Then I'll post the "fish room" pics.

Jason, what day/week are they at right now?
I am just wondering because if I recall our hatches shouldn't be too far apart in age. I am currently at 5 weeks, and haven't seen any loss in the post metamorphsis stage yet. All the ones that I have lost so far have been pre-meta. Basically, I am looking to see if there is anything that I need to look forward to in regards to loss.

Day 31 or 32, yours are a few days older if my memory serves me. I wouldn't worry much about yours, these two died because I screwed up...or temporarily stopped thinking, you pick
I had just (I'm talking five minutes before) changed 20 gallons in my 100g. Then I thought "hey, while I've got all the stuff out, I'll move the fry tank. Drained it, moved it, and added 5 gallons of the water from the main tank. The pH jump alone probably did them in, but there was probably a slight temp difference also.

Doh... I am a bit afraid to move them from their larvae tank just for that same reason... I think what I might do is a lot of testing for equipment to make sure everything matches before I move anyone over...
Good news is that I finally have a nice size comparison of one of my kids...
I am currently sitting at 19 I think, possibly 20, but I have little way of finding an accurate count unless I move them into a new home....

Cool pic WW, yours are about 1/16" larger than mine and a week older or so. That's pretty good growth rate.
Steve, I'm still shocked that I got any to survive. I do beat myself up when I do something stupid, but only so I remember not to do it again. All in all, my excitment over the few successes FAR out-weighs any dissapointments.

Well, since I posted video of the new babies today, I couldn't leave the older ones out, they get jealous you know. Still have 7 of them.
