----ok, here you go. I pride myself on fish. I am decent with corals and other stuff, but fish---------well i am the man....
Clowns are easy, real easy. First off, you have too many durn snails and hermits for a small tank. Get rid of half of them, trade them at the LFS and get some salt---that is just unnecessary.
23 total crustacians--make it 10 keep the same proportions so they will get a variety of nuisance algaes out but not so many--------now to the question
Rotifers-------worthless to the clowns-----more for filter feeders-------dump them
Brine shrimp--------nutritionally worthless----like eating mcdonalds french fries as your staple-----dont bother just dump the brine too
Mysis-------perfect-------depends on how big the clowns you may have to chop it up(look into the brand piscine energetics) it is the best with 69% protein
Daphnia-----dump it if it is just for a couple clowns----they wont even know its there
Ocean plankton and krill not bad but if you have mysis it is way better
My advice-----Piscine Energetics mysis or another brand if you can get this brand, also, clowns love frozen cyclopeeze, also formula two flake food
Clowns when disected(wild specimens) have been found to contain up to 40% algae content in their stomachs------
Get some selcon and zoe
Try this regimen----Mysis(piscine energetics), rinse off with tank water(tank water only not top durnit), drain off water and add zoe or selcon and let sit in fridge for an hour and feed
Also, get frozen cyclopeeze and formula two FLAKE(will give him some green in his diet and they love it) Feed the mysis twice a day. Every other day give them F2 Flake or frozen cyclopeeze in place of the mysis on a rotation
One day Mysis, Mysis(enriched of course with zoe or selcon or both), next day mysis, cyclopeeze---next day mysis, F2 flake----next day mysis, mysis
you dont need to enrich the cyclopeeze or F2 flake
I stongly suggest dropping everyting you have, particularly the brine, daphnia, rotifers(are you speeking of copepods/amphipods these are good of course) but if speeking of phytoplankton dump ti in the trash its not necessary
If you stick with OPlankton and krill(sigh) enrich it with Zoe or selcon or both
Get some cyclopeeze(frozen), F2 flake, and Mysis(piscine energetics or the current brand if you can tget it), zoe and selcon
Watch how colorful and healthy your clowns will be as well as they will grow fast
you could do 3 small feedings a day but i wouldnt
do twice a day one like an hour after lights on and one a couple hourse before lights off
