Identification help

[reefjonny]

Hello All - I have a 50 gallon AIO reef tank as my main tank also a small 5 gallon tank as a pest tank. The pest tank has several things in it such as Glass Aneomes, different algaes and other pests I keep out of my main tank.

Last night, I was doing a touch up and noticed this (pic below) any idea what this is?

- What is it?
- Is it good or bad?
- Anything else someone may know?

Not sure what you’re referring to. If it’s the plant, macro algae known as codium

maybe briopsis, hair algae, or some kinda macroalgae

Thanks....always something I have never seen pops up and unfortunately...it's never good! This is briopsis for sure.
