They eat rotifers, for the ~1st week, then baby brine shrimp, till they're big enough to eat flake food.

Fry must always eat "live" food first, in the correct size and soft enough for them to consume. Only Rotifers fit this criteria, and even these need to be gut loaded with phyto and Selcon to increase the nutrition value.

7-10 days of Rotifers, phyto in the water to keep Rotifers alive, I doubt you will have much success outside of this....

Even newly hatched brine is to big and to hard for them to feed, but they will chase and attempt to bite.

Copepods of the right size and especially copepod nauplius stages are far better than rotifers and have the benefit that they are generally more nutritious even if not "gut-loaded". The only issue with copepods is that they are far more difficult to culture in the quantities you would need for a full hatch of Amphiprion larva.

As for only live food - clownfish (ocellaris / percula) fry have been successfully raised entirely with dry food.
Here a source for dry larval feeds: https://pentairaes.com/products/aqua...ed/larval-feed.
I know that the Otohime larval feeds have been successfully used to raised Amphiprion larva. You may however need a special tank - round with laminar rotational flow or a planktonkreisel - to make these feeds work.

And I have raised ocellaris and percula fry entirely with brine shrimp nauplii and frozen copepods. And not just a few but repeatably 90 to 95% of the entire hatch. Though the trick with this was to keep the parents and the fry in a lower salinity of 1.019 to 1.016.

So yes, it is definitely possible to raise percula and ocellaris fry without rotifers.

I used the same and it works, though I didn't find the bucket too effective. The biggest issue is that it is difficult to gauge the culture density.


This is the kind of tank design I would use for the clownfish larva tank:

You want to keep the larva in motion and give them the impression they can swim a continuous straight line without hitting a wall or getting stuck in a corner. Jellyfish tanks like the above are also well suited for many marine fish larva.
