i have a 90 gallon and i was wondering if i could get some type of toby puffer? Its a FOWLR tank. For tank mates i have 3 green chromis, 2 tru perc clownfish, 1 royal gramma, 1 lawnmower blenny and a yellow watchman goby. I have 2 cleaner shrimp and a pistol shrimp with other inverts. My other question is if i can get one will they eat my shrimp?
