A Nazareth man faced multiple charges Sunday after he was arrested for allegedly firing a gun during an argument over whether to allow a hermit crab in a house.

Mario Ramon Maisonet, 32, was accused of shooting the car of his fiancee’s ex-husband, which contained a passenger at the time, after he argued with the man over whether or not a hermit crab would be allowed inside his home, the Morning Call reported.

The hermit crab belonged to Maisonet’s fiancee’s son, who was arriving at the house after a weekend visit with his father, and was in a fish tank at the time of the incident, the Associated Press stated in an article reported by Philly.com.

Maisonet, who did not want the hermit crab inside, allegedly fired the gun and struck the front left wheel of the ex-husband’s car, the Morning Call stated. He also allegedly threatened the ex-husband and that man's girlfriend with the gun.

After the incident, Maisonet was arrested by Palmer Township police at his mother’s home, according to the Morning Call.
