Well, seeing as you asked Marc... YES
You can hardly attend a catfish convention in Wigan without paying a visit to the catfish 'mecca' just 15 minutes down the road... Pier Aquatics.
I have been hunting for male specimens of Trachelyopterichthys Taniatus to go with my females. I asked Neil some time ago and he came up with the goods in a big way. He now has this fish in stock, from Colombia (orange and brown) and Peru (cream and brown). So I have the males at last.
I also bought 4 Leptodoras Jurensis

.
I'm quarantining these fish right now and I will post photos in a few days all being well

. Heck! I hope they are okay!!! They look good so far, but there's very little information to guide me on this fish.
It must have been a year or so ago, when I think it was Steve Grant aka 'the darkone' mentioned this fish on PlanetCatfish and I was knocked-out by its unique looks. So, again, I asked Neil if he could get them. And I waited.
But that's just 2 species from the current extensive catfish stock in Pier. This isn't intended to appear like an advert, but there's no denying that in the UK this is where you go to find the fish you really really want.
