I just won a 28g JBL Nano Cube CF Quad!

Anglers are easy to keep. But they will eventually outgrow a nano cube. I would definitely have one if I had my way! They are certainly unique.
Ya, it looks like for both the horses and the anglers I'd be pushing the limits a little bit.
Either looks perfectly doable from what I can tell but I'd just have to be extra cautious about keeping up with water changes and such.
A few of the anglers at liveaquaria are listed as a 20g minimum and this tank is listed as 28.
