About FishWiki

FishWiki is a community for aquarists keeping fish tanks at any scale, from first-time setups to complex established systems. Members share photos and observations, ask questions about specific species, and trade practical advice on filtration, water chemistry, stocking decisions, and tank maintenance. Common topics include diagnosing sick fish, managing algae blooms, cycling new tanks, and choosing equipment.

The server has learning resources for newcomers figuring out what they need to get started, alongside experienced keepers who can walk you through decisions as they come up. Whether you're troubleshooting a problem in an existing tank or building your first one, you can find direct answers from people who actually keep fish.
