i had water in the tank since last week , when i found out the eggs in the tank ,
but the water still isnt good yet

exactly , it should be set up PRIOR to the hatch, you dont have food so they are as good as gone, a miracle could happen and you get lucky on one surviving , but they need food....which you dont have

Realistically it runs most people around ... $200-400 or so, if you only want to raise a few it can be done relatively cheap.

Not particular hard as a hobbyist, but not easy if you wanted to do it on a commercial level

Phyto or substitute
Rotifer
BBS
Baby food etc

a few failures on rotifer culture

im broke now to spend $200 +

does JL sells Rotifer ?

I would say you should probably not even attempt this until you can have a proper set up and rotifers before starting. From what I've read, you need a fairly stable system to hatch rotifers and alot of them ready once the eggs hatch. Then you need live brine and this is done separate from the tank the eggs are kept in. This should have been ready before they started to hatch as they need to eat almost constantly.

well my brine shrimp is ready , and idk where to buy rotifers and the other tank had water in it witha powerhead and blue t5 on 24/7 but the water was shallow water
the water condition is almost fine

I finally had a moment to chime in a bit.

I apologise if I have repeated any information;

The key to raising any fry is the food, and the combination to give the maxinum nutritional value for the buck.

I will list the most inexpensive methods for the following;

You need Phyto to feed rotifers, phyto can be cultured in a 2L pop bottle with a little air movement, and light. To feed the phyto you need a fertilizer, G2 or F2, or even miricle grow (not recommended)

You need a good concentration of rotifers to even attempt the first 24hours after a hatch, if not they WILL starve to death. This needs only a 5gallon pail, with an air bubbler. When the rotifers go yellow, add more phyto.

The rotifers should be set up at least a week in advance, they pail should go from green to yellow at a depth of around 5" every 24-48 hours. If it doesn't, you do not have enough rotifers.

clownfish will hatch out from spawning date between 7-9 days, depending on your species, and the temperature you have them in.

They should be removed from the parents tank prior to hatch. You can use tank water or make NEW seawater for this. The eggs are more resilient than the fry to changes in water.

I've been told that Baby Brine shrimp can be fed after 6 days, I have done as early as 3. THEY CANNOT EAT BBS ANY TIME BEFORE THAT, rotifers are their first foods.

After the metamorph stage (7 days), they can start eating other foods.

thanks all
but all gone i dont know where did they go , or whatever ate them all

this is the livestock i have
1 Dragonet Mandarin Spotted
1 Goby yellow watchman
1 Fire Blood Shrimp
1 shrimp pistol
and a pair of percula clownfish
i see the female keep open and close her mouth

you'll never be able to rear larval fish in a tank with other fish, adult omnivorous inverts.

also, most filters are good at eating larvae.

If your parent pair are in good spawning condition, they'll spawn again in as early as 2 weeks. If you're interested in getting serious on rearing, time to start culturing phytoplankton and rotifers... you might be ready in 2 to 3 spawnings from now. Good luck.

Actually, with new spawing clownfish it is good to leave the first few batches. They will be larger everytime.

Try to put a tile or clay pot near where they spawned last time. If they are going to spawn again, it should be withing 4-5 day from now.

The female is capable of laying eggs every 14 days or so, but sometimes they take a break for a month or two also.
