Am building some new vivs from plywood

any suggestions about what to use to seal the wood or can i leave it untreated?

was gonna use yacht varnish to waterproof it but unsure if this would be toxic

any help greatly appreciated

yup yacht varnish is ideal, will need leaving at least 3 weeks before using so the smell is gone though.
