Why go to all the trouble of getting new species added when some of the cool fish already on the list aren't imported?
Amphilophus [syn. Cichlasoma] festae, or the red terror is on the list but I've never seen them here. If you're interested in importing some cool new cichlids try convince someone with an import license/quarantine facility to bring in some from Jeff Rapps (www.tangledupincichlids.com). I'd be the first in line to buy some if you could!!
Another possibility for something new thats already on the list would be a barred midas (Amphilophus citrinellus), also available from Rapps and legally allowed to be imported, but again I am yet to see them here.
Crenicichla lacustris (Pike cichlid) is also on the list, but again not available here.
You could probably fudge things a bit and import some young dovii as baby jags, or juvenile Uaru fernandezyepezi imported as U. amphiacanthoides etc if you're willing to take the gamble. [obviously myself of FNZAS would never condone or suggest such behavior, I'm merely pointing out that it would be possible given the similar look of junenile fish and the ignorance of certain authorities...)
