Aquariums are most often associated with fish, but there’s a fascinating world of other aquatic pets that can thrive in your aquatic environment.
These creatures not only add variety to your tank but also bring unique characteristics and behaviors that fish simply can’t offer.
Whether you’re seeking something low-maintenance or a pet with a bit more interaction, there’s an option for every aquarist.
