A fish pond artwork which could be used as is or repurposed (Loughton IG10)

This is something our son made for college but does not want to keep. It is a wooden box made up to look like a fishpond with a perspex "pond surface". It is 40 cms/15.5" x 50cms/19.5" x 8.5cm/3.5". It has a green front and black sides. The "fish" inside appear to be card. It is quite well made, so it would be a shame to chop it up for firewood or something, so it could be repurposed.
