lol idk, i have so many pods in my frag system, there's no way a mandy could eat all of them (4 20longs with a 125 sump. the sump is filled to the water line and then some with live rock).
as far as if i add damsels, they would be the only fish, its a frag system, not a display fish tank. whatever fish go in are there for a purpose (eating flatworms or the like) so something like springeri damsels might be an option, although all the ones i have seen have been lazy and never ate them. so maybe a 6 line or something similar. i havent made up my mind yet.
fish free is another good option on the off chance some fish parasite hitches in on a coral and makes it past the dips and such, that way it doesnt have a host and will hopefully die out faster.
