Question: Is there any wrong with keeping a Buddha statue in an aquarium in my room?
Answer: While a statue being in a room is alright as long as nothing disrespectful is done in there, as the aquarium is with fish waste, it is not considered respectful to put the statue in it.
As Buddha images are meant to represent presence of the Buddha, it is best to place Buddha images on proper shrines as central focal points of reverence and inspiration, instead of using them for mere decoration elsewhere.
