I'd write them an email saying that since fish and birds are pets, that they aren't allowed per the terms of the lease.If you want to give them permission, require them to sign an addendum with additional pet fees, if allowed, or a higher rent or deposit, and at least required renters insurance to cover any additional damage that the deposit won't cover.I live in independent senior housing now and our lease says not fish tanks over 10 gallons.
