So i bought a christmas tree porite and when i was acclimating it i noticed a tiny snail on it aswell as 2 tiny almost transparent spider looking critters. I cant get a pic of the spiders they are super tiny and the snail is hard to see. It whitish with some black dots following the spiral pattern of the shell. Tried to get good pics but its the best i could get. Thanks

Always dip your corals. The spider looking things hopefully aren't zoa spiders or acanthastrea spiders.

Looks like a collonista snail (good clean up member)

I Didnt dip because from what i read online christmas tree worms wont make it after a dip. I did inspect the rock really well and didnt see any other pests on it.
