Clear coat for fish tank

Question
Hi,
I am interested in setting up a new fish tank, a two gallon cheese ball container. It sounds like a bad idea from the start, but i figured that if I cleaned it out well enough, I could use it as a nice fish bowl. The problem lies not with cleaning it out, but with the fact that the container that would make an adorable home for two goldfish that I plan to name Cheeseball and Oilgrit, is (no big surprise) made of plastic. I did a bit of quick research, and found that the container, which was made of recycle #1 PETE plastic, would leach toxic chemicals. My question lies with my solution. Is there some variety of clear coat that is fish tank safe that I could put on the inside of the container? I've searched around a little bit, and haven't managed to scrounge up any valuable details. Any information you can give will help. Thank you for your time!

Brenden,
I apologize first for being so late with this. There have been many complications on my end.

Hmm.. I really cringe at the idea of using the Cheeseball container. I really don't know of any clear coat that is safe for fish and reliable enough to trust longterm that it will not eventually deteriorate in the water.

This really sounds too risky especially when were dealing with live fish. I would just use a glass container. They make quite large plastic fishbowls in the 1gal range and even bigger. But plastic is never as clear as glass and it can be harder to clean.

I would save yourself a lot of trouble and prevent danger to any fish by just using a container specifically made for fish. I also would recommend keeping a betta instead of goldfish. Goldfish are actually best suited to large fishtanks or ponds. They require a good amount of oxygen, plenty of room to accomodate their rapid growth, lots of water changes and good feeding to truly thrive.

Bettas don't require oxygenation, don't outgrow small tanks or bowls, and require much less room and water changes. You still need to know specifics on their care though. This website provides plenty of good info -

Good luck I hope this helps!
