well at first they were horrible because they were the first fish i got and they were territorial....(back when i had my 20 gal) but when i switched them over to the 55 they lost that trait but they do pick on other fish that get introduced into the aquarium after words. and i don't want to hold any information back but these guys did kill my blue tang. problem was that tang was slightly bigger than them. should have gotten a bigger tang. so i you might want to think before buying these.


Great starter fish though
