What are some monster fish that are safe with plants?

[HUKIT]

maybe a pearl gourami

Maybe also a peacock Chichlid

Godzilla! He's a protector (some times) of earth and wouldn't harm any plants in the water. Maybe a few trees, bushes and buildings, but nothing serious to aquatic plants.
Feel we need a little laugh or smile once in awhile.

We went from looking for monster fish which led to pearl gouramis, a random haplochromine, to a 164ft Kaiju. I think the journey is complete.
