Just got to throw a shout out to the chromides, both green and orange. Yes, there is such a thing as a brackish, dwarf cichlid. Oh, yeah, and they're Asian, too. Definitely an oddity. Been many years since I've seen one, but nice fish. Used to be pretty common, not sure what happened to them.
Oh yeah, sticklebacks, too! And pickle weed! Brackish is limiting, but very cool, too. I'm a fan!i
