This enclosure earned its spot on the list strictly due to its tiny footprint, making it a smart choice for cramped workspaces. I find that the crescent shape offers a pleasant viewing angle despite the modest scale.

2. Aqueon 00800198: Aquarium Kit BettaBow Led Blk 2.5G
This setup suits the aquarist prioritizing safety who wants a bit more breathing room for their pets. I consider this the gold standard for desktop split enclosures because the extra gallons buffer against sudden water quality spikes.
You still need to source a separate heater since the kit leaves temperature regulation up to you. My assessment is that the generous capacity outweighs this minor missing accessory.
Reviewers consistently highlight the generous capacity as a major safety advantage for territorial fish.
Many buyers point out that the included LED lighting brightens up the display nicely.
Customers frequently mention that the overall build quality feels remarkably reliable for the price.

Choosing Between Them
If you want the Best Overall Setup, my top recommendation is the Aqueon BettaBow because its extra capacity provides a much safer environment for territorial fish. You will still need to purchase a separate heater for proper temperature control, but the added water volume gives you essential margin for error.
For office workers dealing with cramped surfaces, the Tetra Half Moon serves as a suitable alternative if you strictly monitor water quality. Keep in mind that nano tanks demand diligent upkeep regardless of which split design you select for your desk.
