[goobe]

hey guys.
so i am able to get a fire shrimp so super cheap. ive always wanted a shrimp (cleaner or fire). Im just worried bc i bought a tiger pistol shrimp. hes already set up a home with my watchman under a rock.
will i be able to get a fire shirmp or even a cleaner shrimp?
i have a 20 gal tank

I have 2 skunk cleaners with my pistol shrimp in a 55g. They get along just fine. Not sure if a smaller tank would make a difference in their attitudes or not.

I have a small peppermint shrimp in my 29 gallon with a watchman/tiger pair. The tiger/watchman were in there for 3 months prior to adding the peppermint shrimp. I Haven't had any problems in 2 weeks, and see the peppermint shrimp near the pistol on occasion.
I should mention though I have a ton of crevices in my rockwork so that everything has it's own little nook to go hide in.

i have a 29 gallon reef with 2 skunk cleaner shrimp in there about a year ago I tried to put 3 peppermint shrimp in and my other shrimp (Which were about 3 times there size) killed all of them. Everytime they tried to come out of the cave they ran into they would get attacked by my skunk shrimp.
maybe it was the size thing I don't know I just know that my shrimp has never attacked anything except for them.
