hey, no negitive comments
Not a big fan of cons, too much attitude for no reward (size, colour, personality etc) *..no offense to the true convict keepers out there*
But they look good and healthy enough.
But, CB, im afraid to say, those aren't really cons and they aren't really dwarves. Like my boy Japes said, rams and the like are the real dwarves, and as previously stated, would be best suited to your tank. (thats right japes, seeings as we're the only boring sods on here who like sevs, we're sticking together lol)

They're an aquarium bred colour morph.
