is this red slime?

[Sagacious]

The red dots spreading around the rock. Its hard to the touch and I tried to suck it out with a turkey baster like people do for red slime and it doesn't budge. I can't even really scrape it with a fingernail. Is there red Coraline that looks like this that it could be? Or anything other than red slime.

That is coraline, most def.

Yep, coralline comes in many different colors including red. The fact thats its hard and doesnt come off is a dead giveaway that its coralline.

Phew, good...got worried I had an outbreak of red slime going on!

 

[uh.oh...]

looks like a sponge to me, but deff. not cyno. The FW version can be green. Whats that on the rocks? Flatworms maybe, planaria?

Worms on the rock probably...I have a DSB loaded with worms and such
