Hi, i have recently become a big fan of mantis shrimp and want to make a nice setup tank for them. i have currently a 75 gallon tank with tons of sand and live rock and want to add a mantis shrimp. wondering if the peacock is the most common one. or if the smaller spear mantis are better. also wondering if i got the smaller spear ones would i be able to have a couple of them in my 75 gallon or still only one, same for the peacock is it only one per tank.
Thanks
Thanks
