Wanting to upgrade

[xtra]

Hi all, I have a birthday coming up soon and i was wanting to spend some money on giving my boys a bigger tank. I have a 23 gallon tank (had to calculate it online ^^;;, and i would like to get them a topper for the tank so they have another level to climb and explore. Also somewhere i can put their food bowl, water, wheel, and sand bath.

Does anyone know if there is a place that does custom wire roofs for tanks ? Because short of buying a taller tank i'm out of ideas ^^;;;
And i don't trust myself to make it myself, rarely anything i build stays together XD

Oh, the dimensions of the tank are 30 for width, 12 for depth, 15 for Height. All in inches. If it helps i could snap a photo of the tank as well.

Oh i found this at an online pet store, its taller than the current glass tank that i have and has the multiple levels that could give the boys some more freedom while i'm not around. Its sizes are: 67 x 36.5 x 65 cm (LxWxH). Would that be a good cage ?
Also here is a picture:

It is certainly great for size and the shelves will keep them entertained - but gerbils love to dig and there isn't much of a tray at the bottom for them to make tunnels.

Also, this low-sided tray will mean that they will be CONSTANTLY kicking out bedding all over your room all the time and you will have to keep topping it up as they do so.

Tanks are much better for containing this digging mess - and it isn't so difficult to find a topper cage to attach to the top. Your current tank is certainly big enough for 2/3 gerbils once filled with goodies - so with an additional caged ares on top would become a palace!

Is there somewhere i could just buy tank toppers ? or even just get a custom one made for them.

Cause i reeeeeeeeeeeeeeeeeeeally want to give them more height to their tank, and i wouldn't be able to build it myself XD
