cam and cookie, I say this partly to stop myself from getting them, but this is a rare fish and a great price. From doing a ton of reading over the last hour (and a bit over the last year), this species is tough to breed, but it's possible. They can be more aggressive than rubros or duospilus, so they'll need space, but a group of 5 should be good to try breeding if you can dedicate that space.
(in other words, get them if you can manage it. and if you do, please try to breed, and please keep a log! we need more info about all these amazing gobies.)
