Algae ID

[fftfk]

I was out of town for a few weeks and came home to what I think are three different types of algae in my tank. I was hoping for an ID and information if they will be a pest or not. Right now they are kind of pretty but know the wrong stuff can quickly become a nuisance.

The first is green bubble algae. kill it with fire (or emerald crabs)

The second seems harmless. same with the third

Thanks. I put three emerald crabs in my tank to help with the Algae. I've heard they can be hit or miss with the green bubble Algae.

The second does seem harmless but is not long for my tank. I've bought a tomini tang and he is eating it pretty rapidly

Look at that crab go!

There was actually a better view of him ripping into the green hair algae but I didn't get my camera out in time..

First Photo. Definitely bubble algae. The green strands coming up kind of look like the start of bryopsis. Has it grown since you last took a picture.

Second photo. Appears to be dictoya.

Third photo. Looks like a form of graciliaria. I have one that grows in a clump style. Kind of like chaeto, except cooler.
