Fish That Fit is a small, independent project run by a fishkeeper, not a faceless company, and we genuinely read every message. If you have a question, a correction, or just want to tell us a stocking story, we would love to hear from you.

The best way to reach us is email: hello@fishthatfit.com. We aim to reply within a few days.

Good reasons to get in touch

• Spotted an error in our data? If a species’ adult size, temperament, or water parameters look wrong to you, tell us. The dataset is curated by hand, and we would rather fix a mistake than let it sit.
• Want a fish added? If there is a species you keep that the stocking calculator does not list yet, send it over and we will look at adding it.
• Found a bug? If something on the site does not work the way you expect, a quick note (and the device or browser you are using) helps us track it down.
• General feedback or questions. Ideas for new features, articles you would like to see, or just a question about your tank. All welcome.

A quick note

We are a stocking calculator and a blog, not a vet or an emergency service. If a fish is sick or your water has crashed, the fastest help is usually your local fish shop or an active aquarium community. For everyday planning questions, though, ask away, and the stocking calculator itself answers most of them instantly.
