I was recently given some N. palmqvisti eggs from a local hobbyist.  My first attempt at hatching them was moderately successful since I did get a few fry, but they all died within about four days. 

I used the same approach I've come to use on my gardneri and australes: I run an air line in the hatching tub for the first ten to fifteen minutes just to break up the peat, then add some green hair algae from an established tank and a small amount of vinegar eels for the CO2 and wait a couple of days.  The only thing I did differently this time was using salt in the water (concentration was roughly 1tsp salt per gallon), which the breeder recommended to prevent velvet.

I don't have any really specific procedure for the first few days and I don't usually have problems with fry dying.  Doing what I usually do, I fed some bbs and raised the water level an inch or or two on each of the first two days.  Two fry died after I did this.  The next day, I transferred the remaining fry to a newly vacant, filtered and cycled 2.5 gallon tank where they also died, possibly from the water chemistry fluctuation although I did attempt to mitigate it.

This is my first time with a Notho species, or any annual species so any feedback is much appreciated!

Hey Jim,

Thank you!  Should have thought of that.  I'll take a look online and I'm sure it wouldn't hurt to get back in touch with the breeder too.  Glad to hear the hatching part sounds good though!

Hello,

It looks like you are doing everything right.

Compare what you are doing against this: http://tgenade.freeshell.org/myfish/notho.pdf

I wouldn't bother with vinegar eels, and avoid water changes in the first week as some fry are sensitive to changes in temp and osmolarity in the water.

I have recently had some issues like this where broods of fry have suddenly died or languished and not grown. I put this down to some or other bacteria in the water and am now investing extra effort to limit exposure of the new fry to the water in my other tanks.  I need to get a new bulb for my UV filter...

Be careful not to overfeed. Any rotting bbs will kill the fry.
