Please help identify these two...

Hello. I am newer to the forums, so I apologize if I didn't size my pictures correctly. We have found these two things in our tank. Not quite sure what they are...the first one was found this morning, and the second one, we have found a few weeks ago, and have been keeping an eye on it. The clear and striped picture actually looks like it has "feathers" in the center. I guess that is the best way to describe it, but it is behind our LR and under other pieces, so it was kind of hard to photograph.

Thanks in advance for all your help

Oops, sorry I just realized the bubble is second and the clear and orange striped pic is first. Didn't mean to confuse you.

Thanks again!

The feathery one I gonna throw out a guess that it may be a barnacle. The bottom pic a sponge. HTH.
