I have a 220 gal tank that I have finally removed the last mantis shrimp out of (He kills everything!!. I let the tank go with just rock for the past 4 months (no other fish fish corals or anything else, just the rockand sand) Late last night I believe I discovered that I have hundreds of what I believe and baby mantis shrimps. They are 1/8" to 3/8" inch long and still have clear (translucent) shells. Is there any type of nature predator I can pur in the tank to eat these suckers?? Do I have to throw out the rock and sand and start over again???
Thanks
