About

Run by someone who actually keeps fish.

Mr Aquarium is a small, curated shop for budget fishkeepers. We stock the unglamorous gear that keeps tanks healthy — sponge filters, air pumps, foam, tools — and skip the 4,000 SKUs of mystery plastic.

Every product page tells you what the thing actually does, what it needs to work, and when you don’t need it at all. That’s the whole pitch.
