bluegill

At the pet store they always tell me that you should have a gallon for every inch of fish, so I would think that you can keep the bluegill in the 10 gallon tank untill it gets too big the get a bigger tank
 
that's kind of unrealistic though, isn't it? Fish are always growing thus they need the size of tank that can accomodate the size of the fish once it hits adult size. Providing such a tank will allow the fish to grow to their natural size instead of stunting them by keeping them in a smaller tank. That inch per gallon rule is pretty much a myth... holds no salt.

a juvenile bluegill (3"-5") would probably max out the bio-load for a 10 gal tank, you would probably have 2 do 50% water changes every day to keep the nitrates below 20 ppm.

by your pet stores logic I could keep a 8' tarpon in a 100 gal tank, think about it. size constraints are not the only factor, think about water volume and the amount of toxins they can contain before they get to harmful levels.

you could keep darters, and some types of shiners and killie fish in a 10 gal, but you must stay up on your water changes, 10 gal of water can go down hill very fast.

my 2 cents
 
I've kept 2 blue gills in a 75 and they were great... except as everyone else says, they are not good tank mates w/ other fish besides themselves

try them with some adult golden shiners, a school of 6-8 golden shiners all over 2" can make a great "clean up" crew (BG are at times messy eaters) best of all you can probably pick them up for $2 a dozen at a bait shop (quarantine them for like a month)
also a brushy nose pleco can often be an ok tank mate but they are poop machines so watch your water quality.

large mouth bass, warmouth, and green sunfish will hardly tolerate anything else in the tank with them, if they wont fit in their mouth they will harass it to death.

if you could not tell native north American fish are my personal favorite
