i have loads of 55gals comming my way from a group of customers who are moving and such...i have been slowly taking in their tanks for lil to no money...and i mean lil(30 bucks is the most i have spent on one with stand and hood and filters so on and so on...whole setups pretty much...granted filters and lights and such arent the best but i got some lieing around plus i buy them cheap so) but i was wondering if a ray would be fin in a 55gal tank. if so what type of ray would be okay in the 55gal. thanks.
