its hard to tell without dimensions but im guessing either a 38g or a 55g considering the steps in stairs are about 10-12" so thats a guestimate as a ruler.
ok---thanks every1! Im not thinkin that its a normal 29---just for the fact that I have one and the one in the add is much longer/shorter then mine---But I dont know what all is out there---so thought that I would ask every1 here!
stair steps are usually 10"- 12" use that as a guide. It looks like it may be a 4ft tank IMO. Also gauge it using the light switch to the right they are usualy 5" "-6" for height. It looks bigger than a 29, but dimensions will tell the truth. The stand looks nice. If it's not partical board that's an ok deal.
