I wouldn't put fish in a tiny container like this... but that's just me.
I guess I should give a little more background for what I am going to use for the tank.
I have planned to use an acrylic beanie baby box ("prized" by betta breeders for juvie "jars"). I believe the dimensions are a 4" square top and bottom and about 7" tall. I am hoping that this will be good enough. I am starting to think that the acrylic that the beanie is made of will be too thin.
I am wanting to make the lid into a light like you would see on the typical aquarium, again, using DIY methods. I don't really like the clip-on lights, I'd rather have one main focal point--aesthetically appealing, but if it's the way that I should or need to go, then sobeit. Also, the lid would serve a purpose in keeping in the inhabitant(s).
I had thought of using low-light plants; maybe an attractive moss(es) on a mini piece of driftwood (I am thinking of using fissiden), a moss wall maybe, maybe a small river stone, a few sprigs of Anubias var. 'petite', and I am also looking for a possible moss for ground cover. I am also planning Eco-Complete for substrate. (I have 2 'spare' bags.) I also have a purple-color stem plant (the name eludes me right now, but there is someone here selling it right now) that I could add for some color.
I have a 'tank stand' already purchased. It's actually a candle holder that I found at a hobby store on sale for 1/2 price. It has a perfect 4' square inset for the beanie. There is also a ledge around the inset that I could clip a light to. hmmm.....
