I have a couple from a clutch I got from Jami just over 2 weeks ago. But I just started really so I'm still a noob. I got my first batch of rotifers from Ocean Marine Sales in covina. You could also over night from Reeds. Ocean Marine Sales sells them for a cup @ $5. I bought 2 cups and that was enough to start. I recommending getting some rotifers ASAP as you'll need a culture going right away. Rotifers can generally reproduce quickly in 24 hours but you still need a lot to feed out. You'll also need either live phyto or a rotifer feed. I'm using live T ISO but some people prefer the use of a product like RotiFeed. Nanno will work when raising clownfish fry, but the EPA to DHA ratio is rather low, so if using it mix it with other live phyto's IMHO.
