Can you ID these guys for me please?

[Solov]

Brown one is hard on touch and thin. It doesn't come of from stone easy - only pieces can be scratched out. (I was trying to get rid of 'em, because they are super ugly).

Thanks!

EDIT: Updated second photo.

the first one looks like an old suction cup to be quite honest, and the second one is a type of macro algae with a little coraline on it. anyone else with a scientific view on these. :badgrin:

Solov - the first one looks like Lobophora variegata - aka Brown Wafer Algae. I have this in my tank, too, and it really sucks.

In the second picture, is that a hard tube? It could be a tube worm, that is covered in coralline, or perhaps a vermetid snail with coralline coverage. Hard to discern from the picture.

 

[Solov]

Thanks for ID-ing! Second does look like tube worm. Are those guys good? They seem to multiply quite fast.

And here's another picture of "brown guys". How do you remove them, Nikki?

Yes its a tube worm, I have some just like it. They algae I dont have a good way to remove, and would be interested to know myself. Steve

I have the brown wafer algae, too. It is a bummer. It spreads fast. I just keep peeling off as much as I can. But, it is disappearing now. I did a major light upgrade - maybe that is why? Or maybe it has just run it's course like most things do?

I think the best way to control it, as with most nuisance algae, is nutrient control.

I don't know exactly the best way or the proper way to manually remove that stuff, except to peel it. If you peel it and look at the underside of it, you will notice it is kind of rough. I see detritus stuck to the undersurface and figure it traps it in this manner to help its growth. I'm hoping that as my tank matures and excess nutrients begin to minimize, it will begin to go away, instead of spread.....grrrrr. I thought I read somewhere that it is often seen in newly set-up tanks (maybe in the link I posted above). Big water change today will hopefully help my battle.

I think the second pic is a vermetid!

 

[Solov]

Thanks, TankGirl! I think you're right, I searched for "vermetid gastropod" and it sounds this very well might be it. And importantly, these are "good guys" , so no worries.

 

[tankgirl]

My pleasure, Solov!
Your pic would be a good one for Nikki's hitchiker project, nice clear pic.

Naso tangs love L. variegata and will strip it in less than one week. Although Naso tangs can become large they don't grow that fast. If you get a 3-4" one it will still do the trick and take a year or so to reach 6-7". They get alosng well with other smaller fish, even other tangs.

HTH,
Kevin

 

[Solov]

Now Kevin, you make me wish there was an unstressful way to borrow a fish from a friend in a mutual benefit of varied diet for fish and me getting rid of L. variegata

I wonder why my Damsel doesn't eat it, because he eats literally anything else , I think I even saw him biting patches of cyano :shock: when I had it (not that it helped to control it in any way though).
