@Palyzoa, agreed good to have!

Nice will they get bigger and will they become a issue with taking over ?

 

[easternreefer]

no.. not much bigger.they usually disappear after a while.. I believe they require silicates to survive..

No worries of large scale infestation with these little guys. They are more cryptic/ don't like a lot of light. Their number will increase and decrease dependant on available nutrients. Live on undersides of rocks, sumps and overflow boxes.

Okay They are all low on the rock down by the sand bed

While I’m on the subject of what is it .
Is this red bubble algae or a micro algae

 

[easternreefer]

yep.. Red bubble.. can be invasive

Thanks @easternreefer
Glad I carefully removed without breaking the bubbles
