Dinoflagellates Natural Selection to Survive UV.

[Miami Reef]

Why do dinoflagellates in reef tanks let go of their substrate every night? Giving up their territory is risky business, so they must have a good reason.

Also, do 100% of dinos (Osteoporosis, Coolia etc) leave their substrate every night, or do some remain? The reason I ask is because if a small amount reproduce and survive without needing to free swim every night, then could potentially make a strain of dinos that never leave the substrate, making UV not work in the future?

Amphidium Dino’s live in the sand and don’t go into the water column at night but I’ve heard they are the least toxic Atleast lol
