thanks sue
the tank is four foot, heated, well planted, i have a fair few cory's of different types, kuhli loaches, black ghost knife fish, some cardinals, rainbows, cherry barbs, borneo suckers and a lonely serpae tetra. I am getting two black eyed golden b,n's, they dont grow very big. really keen on a cool plec, that will show up well, get on with all and not too likely to die on me!
Thanks!
