First pic looks like a majono (better kill them) 2nd pic is tubbs blues 3rd looks like gobstoppers 4th one, not sure..looks like a common no name z 5th one looks like devil armour
I mean i guess it could be a mini bta, but ive never seen one the size of a z or p. it's pretty tiny and i would worry about it spreading...even bta's can be a problem if not controlled '
