Feather duster population

[jacksonimaging]

Is there a "magic" number of large (Hawaiian) feather dusters in a tank. Like a Gallon per inch rule. I have 2 large and lots of tiny feather dusters in my 38 Gallon. I do add phytoplankton and ZooPlex Invertebrate food. I love these guys but I don't want to go Put to many in there. Thanks.

as many as you can fit. they have a very light bioload but you will have to supplement the tank with something like phyto or reef chili, reef snow, etc. i think they like phyto the best.
