Algae ID Pls!
 

I found this Algae starting to grow recently in my tank. I cant find a definite ID on it. Its probably harmless but I would love to know what it is! Its texture is soft, slippery and very rubbery.

Looks like plating coraline

Looks like something from the Peyssonnelia sp family.

Thx for the replies guys! Plating algae is hard, this stuff is soft and rubbery. Its "leaves are flat" so it wont be bubble algae either. I had a fella pm suggesting its lobophora, something I'm gonna have to contain before its an issue. Link below shows a couple examples in the last row of pics. They can vary in color even though they are considered brown algae.

This belongs to a type of red algae known as Meristotheca sp. early stage contains beautiful bright red with light orange/gold mesh like pattern when take a closely look. It will change to a darker or deep red color when getting bigger depends on the water condition in the system. A nice decorative algae in reef system unfortunately can be eaten by tangs and rabbit fish. Trimming is required when growing big for it can reach over 8" x 8" easily & blocking the light and killing the photosynthesis coral underneath. HTH
