Just get a few clean glass bowls or old CD packages, dip some water into it, insert one coral/anemone apiece, cut the lights, cut the pump, get a stepstool and two nets and go after the critters. Have extra containers ready for them. You can try traps, bait, hooks, all sorts of things for days on end, but with so little coral, just go get them. It will take you all of half an hour to have them out and have your tank back in business.
