Not sure what this is?

I just started getting this dark maroon stuff on my rock. I assumed it was a slime algae but it seems very hard and won't just rub off with a metal object or anything. Seems too dark to be coraline. Any ideas?

thanks

I have dark red coralline - if it's hard, I'll bet that is what it is. There is also a type of red mat algae that has a similar color, but it peels easily off of the rock.

Have you considered an emerald crab for the bubble algae?

Love those blennies! Mine hides in a hole in rock, too.

I also have some of that dark red coralline. And my bicolor blenny also loves every nook and cranny in the rocks that he can fit in.

I too, have had dark dark wine colored coralline on my rock. If it's hard and isn't easily removed that's probably what it is.

Love the pic BTW

Thanks I don't mind it,, just didn't want no more slime algae. It just seemed very hard, I have an emerald crab I just got a couple weeks ago and he loves bubble algae LOL. Thanks for the help

I loved my lawnmower blenny but he died , is bicolor blennies better?

Bicolors have lots of personality and mine, at least, will eat anything placed in the tank as well as graze all day on algae. Great little beasties.

I really like my red blenny. He has loads of personality and pretty much does what you folks are explaining your bi-colour does.
