Sunrise Dottyback eggs/larvae

[clownfish75]

HI All

Well surprisingly my trio of sunrise dottybacks (pseudochromis flavivertes) worked and 2 days agoa pair of them spawned.

the egg mass is basically clear, as it is in all the pics i can find.
there seems to be some darkening of the eggs perhaps eye development (fertile!!!)

i found info saying it is about 4.5 days to hatch at 25oC, i am running 27oC so assume it will be on the 4th or 5th night.

my question is to those who have played before, will 60-100 micron rotifers be a suitable first food for those first 10 days? will enrichment of them with rhodomonas, t-iso, nanno, pavlova help with the larval survival?

how much are bacterial problems a real issue? should i buy some streptomyacin in preperation? what day would i treat with this? will it kill of all the biofilter bacteria?

Thanks

At 80-82F , they will hatch in four days with some of the larvae forced by the male during the evening of the hatch just before lights out.

B plicatilis will be fine

it will help but you will benefit more from sleco/selcon enrichment

bacteria attacks sometimes, it can be done without antibiotics but it won't hurt using them.

what day would i treat with this?

I don't know your system but in my experience from day 7-10 sometimes longer

will it kill of all the biofilter bacteria?

It will cease as long as you dose it, what filter??

thanks for the tips Ed, the biofilter is a fluidized bed filter in a remote sump. tank has flow through each night.

I have never tried enriching rots with erichment medias, normally leave it for artemia, but you do do it to the rotifers for dottybacks?

Thanks

The filter is not going to help you with a genus so prone to bacterial infections, the best way to keep nitrogen down is with water changes.

The first 10 days are crucial for the deveplopment, I have not done it but I think is very unlikely to get many through without enrichment.
