ok so im turning a gum ball machine into a small aquarium as a gift and im taking the glass into the glass company tomorrow to get a piece for the bottom . any suggestions as to how thick to make the bottom so it wont crack under the weight of the water and sand. also silicone what kind should i use thats good?

oh boy do we need pictures!

Any guess at a suitable thickness would require knowing the volume of water we are talking about. There's no way around that.

Also how do you intend to facilitate gas exchange & filtration in a closed system? Or will this be open top?

Is the giftee an experienced fishkeeper? Aquarium safe silicone is available at any LFS.

small vivarium could be an option

I would suggest before you get too far along, to research fish that could live in that size of a bowl and what you need to modify to the bowel in order to provide for the fish. If I was you, I would want to make sure all your efforts are going to be worth it before starting to work on this project

DAP makes some silicone that is aquarium safe.

it will be 1-1.5 gallons
its going to be an open top, im putting a beta in it
shes had betas before but obviously is not an expert
thank you

Hate to say it, and I won't be the only one to say it, but 1.5 Gallons is not enough for a betta (even if a fish shop says so).

It would be considered cruel to keep anything in that size of a bowl, especially without any sort of filter or heater. I would say it may be best to toss the idea, as cool as it would be, this size really wouldn't work.

Agree. No fish wants to spend it's life in a one gallon tank.

As cool as an idea that is, i would have to agree with everyone else, that tank is a no go for fish. However, you could make a very interesting closed ecosystem with it, using some plants, dirt, and a bit of water. Would still make a great gift, and has a ton of educational value about how ecosystems work.
