I am setting up a 215 gallon planted tank, which was origianlly designed as a reef tank. I have a 35 gallon sump i was thinking of setting up as a refugium w/ plants on a reverse light cycle to the main tank.
My question, is, in saltwater, small critters we want in our main tanks are usually sucked out of the refugium in their juvenile/larval state (copepods, amphipods) and dont recieve much damage from the filter, if any. sure, every now and again, one will die, but enough make it through to enhance the display.
So.. if I set up a system where the adult shrimp are isolated, but the newborns can make it past the isolation barrier, say, a baffle, what are my chances that they will make it through the return pump and into the display tank intact enough to grow to maturity?
I am trying to figure this out, obviously because i like invertebrates, but i am going to be keeping fish that will emjoy having shrimp to graze on. I don't really care if they get some, or most in the display, as long as some survive. The display will be heavily planted, foreground will have huge patches of micro-sword.
I am hoping enough shrimp will survive in the display i don't have to worry about a refugium methedology, though i am not opposed to setting one up if it will work.
OH, my planned stocking list is the usual suspects cory cats, britsle noze, ottos, etc... primary fish will be discus. and at some point, I might risk putting in a bichir, though it might mean the end of the ottos, i suspect it would decimate the shrimp population... but, every bichir i have had before seemed to love ghost shrimp, so i was thinking, if i put in smaller cherrie shrimps in the fuge, and ghosts in the display, the ghosts would be the preferential food for the bichir since they are larger and slower...
anyhow, thanks for the advice up front!
