I'm in Central Iowa. I do think there are several forum members in E and NE Iowa. I don't think anyone that I've seen post (although I've been on less frequently since school started in August) is a breeder in Iowa though.
That is why i won't go to the fish shack in Manchester. They are nice and will cut a deal. but it seems so dirty, smell, birds look like in stress, betta in like old glass jelly jars, the boards holding the tanks look like they will collapse at any time, and and the salt water tanks look like its leaking everywhere. I won't go to Petco due to thru huge issue when i ordered online for my tank. It was to be shipped out next day it took over a week to even ship then i didn't get everything.
I'm from Iowa, there's a club of sorts in the Iowa City/Cedar Rapids area, I never went to their events (Social Anxiety FTW!) they do a lot of swaps. I'll try to dig up the name... it was given to me by the Petco here, the head of the Aquatics/Companion Critters is frickin' phenomenal and hooks me up a lot (I couldn't handle a job there though ;_;)
