hey im in the down town chicago land area as well! ive been to a lot of local fish shops. Old orchard aquarium they have cool tank set ups and displays. thats where i bought my 24dx nano cube. their prices on fish are decent, coral prices are pretty high, and accessories are ridiculously expensive. i usually go to ocean design. you know about that. o yea theyre were having a 25% off coral sale on thursday, maybe their stuff is still on sale. and they said 15% off fish starting monday. ive been to aquatica in tinley park. they have some cool stuff, nice frag tank, but prices were a lil pricy as well
