hello my name is Alex and i live in chicago, just registered yesterday because i wanted some expert advise since you cant find that at petco....anyways bought this tank off some guy on craigslist about 3 months ago...it came with 70 pounds of live rock, protein skimmer for 90 gallons, two heaters...as far as fish go i have a porcupine puffer small size, a maroon clownfish, dwarf lionfish, niger trigger medium, sweetlips clownfish small, a foxface medium....they all get along well they dont mess with each other they are all eating.....i was wondering if they will be ok in my tank or how long i could keep them there before i would have to buy a new tank...i really like all these fish would really hate to part with any one of them.....
