Question on acrylic

[Ink]

I have a crack on my acrylic tank side. It is in my tortoise enclosure, so it doesn't hold water. I don't want it to keep cracking. Can I just use sealant (used for aquariums) to seal the crack or do I have to drill it too? Thanks

As long as you don't want to use it to hold water, then yes, I would just put the sealant over it.

Thank you very much! I was worried about drilling it.
