Whats this?

I was just admiring my tank and noticed these red bubble like things on the rocks. I've never seen this before and I don't have it in my other tank. Trying to figure it all out BC I'm about to take these fish an rocks and put in my 55 gallon tank. Thanks!

Cyano bacteria maybe

 

[J19Reynolds]

Is that bad?

 

[Ga1981]

If is cyano you want to removed... Can't really see the picture.

Came off the rocks easily?

 

[J19Reynolds]

I haven't tried to remove it just yet. There are only 2 fish in there one peppermint shrimp n couple snails.

Should be coming off the rocks easy, and if is cyano you want to removed ASAP.

Red bubble on rocks sound like cyano to me,
You can google it,maybe too much feeding or too much light.
Check your parameter too, it can grow quickly...
