Identification help

CanDo · May 28, 2022

Hello friends . Idk if this is the correct place to post this and I apologize in advance if it's not..
I'm just trying to identify these little red rings on some rock I was gifted. They're pretty soft to the touch and are a deep maroon color under the fluval 3.0. they're about 1/4 inch round. Any thoughts? Cheers

Could you get some pics underwater?
Looks like it may be red bubble algae. I have it in my tank, even the emerald crab doesn’t go after it much.

Hey sharkbait19. I guess I could put it back in... I took it out in case it's harmful. Thanks for the reply

It’s not going to release chemicals into the water, just likely spread fast.

Hey sharkbait19. Sitting on a well lit shelf for 30 mins. Thoughts?

Very common on rock that has been in environment with elevated phos and nitrate at one point and known as foraminifera which is sponge like. Can be picked out with a blunt tip . Ninja star snails eat thi

Awesome, thanks for the knowledge vetteguy. How freakin cool, AMEBAS! Should I just remove the rock? Is it harmful? Does it spread?
