-- What's Everything ducks ? .................... Oh, you mean sucks. That's sad.
-- You mean exotics that people keep in aquaria? I don't need tilapia and plecos and red and green terrors etc. but I hope you mean some others. And where can this can be accomplished (I do own a cast net and practice often - all my fish eat out of the Gulf of Mexico...)?
If you ever sneak over to the west coast Naples FLs Reynas Aquarium is a nice little shop, mostly cichlids and lots of oddballs. He's got a 2 ft+ RTC in there he's had for quite awhile.
He usually has in lung fish, knifes, oddball cichlids, butterfly fish, rtcs of various sizes, elephant noses, tiger shovel nose. Lots of cool stuff. Very small store but worth the trip imo.
