Last night i check my tank before i went to bed. when suddenly i see this 1 small snail crawling on my rock, so i remove it ASAP and surf the net about snails and i found out that was a sundail snail or box snail i think.
Identification
A snail that is regularly encountered in the aquaculture and aquarium industry is commonly referred to as a Box or Sundial Snail of the genus
Heliacus. They have a classic shaped shell that is round at the base and twists upward into a point. Tan and brown colorations alternate within the striations of the shell, giving it a rather beautiful appearance.
Signs & Symptoms
The Box Snails are guilty of consuming many different types of colony polyps within the
Zoanthus,
Palythoa and
Protopalythoa genus. Many times the snail will be found within the colony itself, where they puncture the base of the polyp, and feed upon its tissue and fluids. The polyp is then basically left as an empty shell, which quickly falls off of the rock and decomposes.
