i have a pork and people will tell you not to put a lion in with them, i would be one of them, i HAD a lion in there for a while but a few days ago my puffer shredded the lion, it was devastating, such a beautiful fish, if i were you i would take one or the other back
and deffinatly no triggers they will do the same,
i would get a nice eel
i hear maroon clowns are prety agressive
in my aggressive i have a long spined urchin, a pencil urchin the size of a baseball, a choco chip star, and a red gereral, a handful of big snails, and im not sure if i have any crabs left for my clean up crew
