ok guys i built a tank a few months ago for reef frags but never ended up yousing it. the tank has a foot print of 72x36 but is only 12" high with a 10" water height. would this be good for rays i would like to have 2 or 3 in it. as well as it is going to be placed in my kitchen right by a window it isent direct sun light but it is a big window as long as the tank is. will this hurt the rays in any way. it is drilled and the filter will be a 55 to 75g wet dry sump. im thinking of putting a full glass top on the tank to keep the cats away and also you it kinda like a light yous table. can anyone tell me if this setup is ok for what i want. can you mix different spices of rays? o it come out to be almost 130g w/o sump
