Ok now I'm starting to worry... I found my mantis about 3 weeks ago. He's grown quite a lot in that time period. Today while I was watching the copepods at the bottom of my tank I noticed about 20 more mantis shrimp... Tiny little things. They look just like the one I caught awhile ago. I guess the rest of the eggs hatched. Now I'm unindated with Mantis'. I'm positive they are all mantis shrimp. They look like praying mantis with their claws and they have all the physical characteristics of mantis shrimp. Not sure what I'm going to do with 20+ mantis shrimp.
