Bought myself a little hillstream yesterday, I thought it was a common plec at first

But found out from Pleco Fanatics it is a Hillstream...what a silly mistake!

Anyway heres the little guy...

Rescued him from a tiny goldfish tank that was only 10 litres...he now seems happy in my 8 gallon which has one tiny goldfish. He likes to hide in the plant pot in front of the filter which I have directed some of the waterflow and aeration into because they like current?
Any other things I should know?
Also what do they most like to eat?
Cheers!
