Hello; A question about the fasteners (screws- bolts- or?) used to connect the lumber. From what I see in the picture it is these fasteners that support/transfer the load to the verticle 2x4's. I cannot tell how many there are. Whatever they are, they need to have enough shear strength. Drywall screws, for example, would be a very poor choice. I cannot tell from the pictures if you have enough extra space to sister in short 2x4's on the inside to carry the horozontal bits.
I tend to estimate the weight of 55 gallon tanks at 10 pounds per gallon by the time all is considered. The water, the tank, equipment, substrate and whatever else that winds up in one.
I ran a 55 gallon tank in an office some years ago. I was concerned about the possibility of a child somehow tipping it over. I attached it securely to the wall. It might also be worth considering connecting with a strap or length of board up to the cielling above the tanks.
