Help identify some LR hitchhikers

[va_riverrat]

Hello all,
Trying to figure out what these are. This is a new tank that has been up for close to 4 months now. I have these "gold ball" looking things growing all over the place. They aren't a nuisance and will probably be removed as I stock but was just curious what they were. The largest are about 2" across and grow to be that size over a 3 week period. they are translucent and covered in fine hair. I thought they might be some type of sponge:





I also have a couple of these frill-looking things. The largest is about 4" across and has light blue and white bands that are slightly phosphorescent. They are neat looking but are in a bad spot right under the light.



Any guesses?

Last pic looks like a form of Algae. The first one might be a softie?

Not sure on the first one. I think the second one may be scroll algae.

The last one is padina, Padina spp. are a common group of brown algae (Phaeophyta) with leafy, fan-like blades. Padina lives on hard substrates like rocks in shallow water. The "leaves" are lightly calcified and about 5 cm in diameter.

The other stuff I believe is another type of algae, not sure but it might be Globe Algae. Not sure what the real name is.

Since you have very good pictures of the stuff, you might try posting in the Marine Plants & Macroalgae forum.

Wow, thanks, that was quick. Looks like you nailed it on the scroll algae. Quick google search seems to confirm it. Checking for a pic on globe algae. I'll take the advice and post in the macroalgae forum.

Thanks again.

Here's what I could find, but it came with a bad picture:

The Globe Algae is irregular in shape, globe-shaped, and crinkled in shape. This algae is sometimes twice as high as it is broad.

It's skin membrane is a thin, crisp wall filled with water and air.

The plant is usually attached to other algae, seagrasses or rock by a small, crusty base. Globe Algae is also called Bubbleweed.

Globe Algae is light yellow or honey-brown to dark brown in colour.

pic #1 is for sure algae

someone just had a piece of that growing in their overflow in another thread. I forget the name. I remember guessing Lobophora, which it wasn't, but I'll guess Lobophora again for this one..

#2 = Padina for sure.
