if i answered last week it would be 5, today though it is 2! I plan to go back to 4 once i figure out how to buff out acryllic scratches

77g - mixed reef (home)
90g - fowlr (office)
6g - pico (hallway)

90 gal display reef with 30 gal sump
38 gal Frag tank
30 gal tank with no solid pupose right now(gonna tear down)
5 gal Zoa/Paly garden tank

My main display is Chin's old 165g starfire with a 90g wide sump.

My other tanks include a 2' cube (60g) "Nemo" tank, a 34g RSM "Favourites" tank with Copperband, Porcupine puffer, Marine Betta & little Canary/Yellow Wrasse. On Felicia's desk are her 2g Fluval Spec Cassiopeia jellyfish tank, her 8g Fluval Flora planted fw tropical & her 6g Ehiem fancy fw shrimp tank. Outside we also have a 180g "pond" for the koi.

BTW, this is severely DOWNSIZED from the OCD craziness of a couple years ago when I was up to 1000g of sw tanks alone.
