My marroon clowns hate snails. If they see any they attack it until they are sure its dead. When they killed a group of margaritas, they did have "smoke" around them. It must be their souls.
Haha we'll hes ok. I just thought it was cool. Despite people saying margarittas don't live in warm water they do great in my 78-82 degree water. So far they lived for 4 months.
