Hi Rich
I have two of these beauties and they are incredible, gorgeous plecs. A brilliant addition to any peaceful tank.
Mine love eating frozen shrimp (but only ever week or two), bloodworm's, blanched courgette, cucumber and my female even eats blanched potato. They are nocturnal, but mine do come out during the day, especially during feeding times.
I paid £35-00 for my male and £25-00 for my female. Got them at separate LFS's. My male was wild caught (so I was told) and the female was tank bred. They tolerate each other, although she does try get his attention, usually with him swimming away screaming.
They get on with my cories, BN, red whiptails. Like I said, peaceful tank. To start off with, they don't like to have to fight for food, but eventually, they come out with everyone else and just eat.
Here are my two sitting together on the cave

I know they're a little pricey, and if you are considering getting one, shop around and make sure you get a very healthy specimen. They are worth it, a lovely addition to any tank.
