Naga aquarium

Dear Pantip readers,

As a non-religious farang I have a question:
I have a customer who wants to put a small Naga statue in his big aquarium because he thinks it's beautiful and shows his connection to Thailand and the protection of the rivers.
He asked me if this is a decent thing to do, or is it a no-go? Something you can do or should not do?
I would love to hear how you think about this, kob khun krab!
