hey guys, just planning out a stock list for my 30 gallon finnex. i already have a false percula hanging out in my 20 gallon waiting for the 30 to finish cycling. i plan on adding a shrimpgoby after the clown and a mystery wrasse as the 4th fish. i just need some suggestions for a 3rd fish, any recommendations? also, if i were to get a shrimpgoby w/pistol shrimp, will the wrasse eat the pistol? i know mystery wrasses are known for eating shrimp, but i have never heard of them eating pistols, only blood and cleaners. maybe they don't go after the pistols because they can defend themselves, any idea?
