I'm not sure if this is an algae or hydroid or what :confused:. I don't want to touch it because i fear i will be stung :twitch: . Thanks for any light you can shed.

A regular picture would help. Could be a digitate hydroid but without a regular pic it's just a guess.

They are digitate hydroids. Thanks! The pic I took under the scope was the last of the battery in my camera and I can't find the charger :/. I found pictures here on RC that are exactly what I see in my tank. Here's what they look like. Thanks again!
