Description

The Guppy Fish Metal Warning Sign adds a playful nod to the fishkeeping hobby, featuring a guppy sign that any tank owner will recognize. Fun fact: guppies are famously prolific breeders, which is why so many home aquariums somehow end up with far more fish than anyone bought.

It's a great gift for guppy lovers, hobbyists, and collectors alike, and makes a fun, low-effort housewarming or holiday present. Every sign is made to order and custom-imprinted in the USA, right in our Henniker, New Hampshire studio.

Does this sign come with mounting holes? Yes – every size now ships with or without pre-drilled mounting holes on the shorter ends, your choice at checkout.

Is this sign safe to hang outdoors? Yes, it's rustproof, UV-protected aluminum built to handle sun, rain, and snow for years.
