Howdy Revill..
my setup is in my basement to get through northeast ohio winter, but is still going well.
down to 2 crayfish, i used "local" crays, and think most of them killed each other but a few may have been eaten by the fish, provide plenty of hides and food if you go with the crays..i'd really like to try "Red Claw" crayfish, but have to wait for warmer weather, they supposedly do ok in higher densities
i added a swirl filter to go with my growbeds last week, and finally got a half decent camera, but my photography skill are a little shakey, here are a few pic's (before adding the filter)

the minnows are doing well (rosy reds), i moved the larger bg (5+") to the yp tank, and hopefully will be able to add more yp soon
