If you can catch that crab and hold onto him until the 6th, I will take him. Maybe he could hang out in a yogurt container submerged in the tank with holes in it to allow passage of water.
I did some research on isopods and found that the young hatch from eggs carried by the females and resemble adults but with one less pair of legs (six versus seven). Copepods, on the other hand, hatch as nauplii and grow into copepodids then finally into copepods. Copepods, throughout their life cycle, are able to swim.
Having said that, there are also parasitic copepods out there. Therefore what you are going to do with the ones you've been catching is up to you.
