Were making a bigger better tank for my lovely Leos since the one we made now is more for Beardies with length and such so were gonna sell it for cheap once the other ones done being made so if your in the MN areaXDD im including with it 2 like 36 inch UV lights which were 40 each! so its a great deal BUT on with the question lol What are the measurements to a 40 gallon breeder tank? A 55 gallon tank? Im trying to figure out the measurements so i know what size UTH ill need for the new tank. I know a 20 gallon long is 29X12.
