All these globes and bowls, tbh, are kinda pointless and a big hassle. They're expensive, not all too functional, and tiny tiny. They're pretty hard to attach a heater to (unless you go out and buy a adapter for the heater to cling onto the side, which looks quite tacky), most of them have a built in filter, if any, and getting a different filter for them is nearly impossible from what I've seen. Decorations for them have to be bought for the product itself, if any of them are usable at all, and said decorations, given the small footprint, are going to be hardly functional, and likely won't be able to provide much cover for the fish to hide if it feels threatened.
There are some standard rectangular 2.5 to 5 gallon aquariums that should be fine on a dresser or desktop which are much more functional, way cheaper (I could get a 5 gallon here for about 8 dollars) they provide a bigger footprint, have more easy to find attachments, a large variety of lids, lights, filters, and heaters, and most importantly, are way better for the fish, given the way the space is utilized.
Granted, even a 2.5 to 5 gallon tank is gonna limit you to pretty much just a betta and some shrimp, but that betta and those shrimps will appreciate the use of space in a rectangle more than a sphere.
