Peacock mantis shrimp.. companions??

[Mrs. Suzy Smith]

What size tank would ya'll recommend if I want to house a nise sized peacock mantis with a clown and a couple blue damsel?

 

[Mrs. Suzy Smith]

Also, is there a species of mantis that is friendlier?

Most recommend a 30 gallon or larger for an adult peacock. I have never had the pleasure of keeping a peacock though so keep that in mind. Friendlier? They all differ in personalities but some species are reclusive (G. chiragra) and are therefore less likely to encounter a tank mate, yet chiragras are reported as aggressive. It's really dependent on the individual mantis and what they are "thinking" at the time. Some are fine with their tank mates for years and then one day something snaps.
