I decided I wanted my first occupant of the new tank to be a Peacock shrimp. Full disclosure, I'm a newbie and my LFS knows this. I called the place and told the owner that's what I wanted for my first inhabitant. I appreciated that he had some concern. The first question was "Is that all you want in there?". Confidently I said, of course not, we will see what happens. I then got a little more specific and mentioned wanting a small mantis. 2-2.5 inches. Something that can grow with the tank and hopefully not see everything in the water as a food source or threat. The tank is 250 gallons. I believe there is plenty of real estate for the shrimp to claim and get cozy with. My question to the shrimp keeping pro's out there is, what are my best options for tankmates? I'd like to get something else to help with the bottom of the tank and etc. Is there anything else I should worry about an absolute "Don't do it"? I've seen some pictures on the forum of tanks with Peacocks and other wildlife, it's obvious it can be done. Is there a secret sauce I should be looking to replicate?
