That's the first I've seen of the "midnights." Given what else is on the market, I figured they'd pop up eventually. Are they percula or ocellaris?
Also, I'm in agreement about keeping the pairs in separate tanks. If after hearing a number of people say the same thing you still insist on doing it; I'd be happy to kick you in the pills and take your wallet. It has pretty much the same overall effect.... It's expensive and it hurts.
Of course if you're female we can go for the "purple nurple" and stolen "purse" route instead.
Convinced yet? LOL
