Re: [Killietalk] N. leuki

N. luekei (note the spelling) has the smallest of Notho fry. Microscopic foods are essential. In my experience they are prolific, laying lots of eggs, but it is difficult to raise large batches. I would recommend collecting the peat often enough that you don't get hatches that are too large. I have had the experience of hatching over 600 fry of this species in one batch. It is then tempting to try to raise them all, which is difficult.

I think the best way to handle them is to hatch as usual into a shoebox or similar. Incubation time under my conditions can be as long as 6 months. Immediately after hatching scoop the fry out and transfer them to a tank containing 4-5" of aged water, with Java moss etc in it to harbor organisms. Establish that tank a week or more beforehand, and possibly even seed it with Paramecium and rotifers. I have even fed that culture with a few drops of non-sweetened evaporated milk to develop a bloom of the organisms.

In my experience, it is a mistake to try to raise these fry in shoe boxes. You might succeed in raising a very small number, but it has not worked for me. The fry can't take newly hatched bs until about 10 days, maybe more.

Good morning everyone.   I've jujst received  two pairs of Nothobranchius
(aphyo) leuki and I would appreciate any help I could get from anyone with
experience with this species.  I understand that the eggs and fry are
smaller than most Nothos, but do they differ in any other important ways?
Temperature or incubation requirements?
Thanks.
George Morris
