fish tank in partition wall

[myfs_119762]

I haveencased myfish tank ina partition wall between my living and dining room. This means SE of the living room and SW of dining room.

Using the five element theory, water in SE is productive but not so if placed in the SW. Is that right?

Please advise if I need to put a screen to 'close up" (visually) the fish tank in the dining room. Thank you very much.
