damsels wont stop spawning

I dunno, from everything I've read in order to raise marine fish larvae you need to get them out of the display into a separate tank to:

1. avoid predation by other livestock
2. feed them live rotifers, for which you need phytoplankton
3. probably missing a number of other points, but

It's quite a work intensive project and as mentioned at the price of the average damselfish, you'll certainly not recoup any of your costs. Could be a fun project though, good luck.
