ID help on 3 things and I'll throw in a sump design question

I had to help out a friend get some livestock, etc out of his tank. I know
three of the fish but these two I'm not sure of. I'd appreciate the help.
I know I've seen these before while surfing but now that I need to know,
alas I cannot find them. (Yeah I was a bit amiss that he didn't know his
own fish either. No comments please on his lack of knowledge or the risk I
could be taking doing this. )

The third item is a worm I've had for a while. I first saw it a few weeks
back and still do every once in a while. I don't have a pic but shouldn't
need one. Imagine a kit string going in and out of your rocks, rather
slowly. It's very white and very thin. I've seen about 4" of him so far.
What I can discern as his head has no eye, or even a shape change that even
makes it look like a head, like many flatworms (such as
http://www.aecos.com/CPIE/flatworm.jpg) do. It just comes to a point. It
almost looks like a really long tentacle from a spaghetti worm.

Any ideas? Gracias de Texas.


Also, instead of posting again I'll ask here. I'm designing a sump that I
want a protein skimmer an refugium in. I plan on planting the refugium to
further eat up the phosphates. Should I put the protein skimmer before the
refugium or vice versa? Does it really matter.

Thanks again,
