Hi, I don't know if anyone remembers but I posted a few months ago about a common snapper that I was given by a friend. Well, I've upgraded his tank to an old 55 i had in my garage and it seems rather dull with just the 5" turtle. I was wondering if there were any fish i could add that he might not bother, maybe something too fast for him to catch or maybe inverts (he isn't bothering the mystery snails in the tank). Any and all help appreciated.
