Tank Mate Advice Please.

Ok so I have attached the plec pic, I think it maybe a sailfin?

There are two like this, however one has a much smaller tail than the other.

And one of these. Sorry for the bad quality, had to resize it from a full tank pic.

Can anyone identify the above fish for me please?

Some kind of Pleco on top (I'm not a Pleco expert sorry) and what appears to be (2) Comet Goldfish on bottom.
