Requesting a missing species
If a fish, shrimp, snail or crayfish isn't in the Fish Species library, you can ask us to add it. Our team checks the care details by hand. When it's added you get a notification, bubbles and the Cartographer trophy, and the species becomes available in the Tank Builder too.
How do I request a species?
- Sign in.
- Open the request form in one of these ways:
- At the bottom of Fish Species, under Don't see a fish?, tap Request a species.
- Search Fish Species for the fish. If nothing matches, the form opens automatically with your search filled in.
- In the Tank Builder species search, tap Request it and earn bubbles (when nothing matches) or Not the one? Request "[your search]" (when there are matches but not the right one).
- Fill in the form (see the next section).
- Tap Send request.
You'll see Request sent and "We'll check its care details and add it. You'll get a notification, bubbles and a trophy when it's in the library."
What goes in the species request form?
The form has three boxes:
- Name you know it by (required): for example "Golden Leopard Dojo Loach". It must be at least 3 characters, up to 80.
- Scientific name, if you know it (optional): up to 100 characters. This helps us find the right animal fast.
- Anything that helps us find it (optional): where you saw it, what it looks like, a trade name or code. Up to 500 characters.
Under the button you'll see "Bubbles + trophy when it's added" as a reminder. Tap Cancel to close the form without sending (the Cancel button doesn't appear when the form opened automatically from an empty search).
What happens after I request a species?
Our team reviews every request by hand. One of three things happens:
- It's added. We create a new species page with its care details. You get a notification, bubbles and the Cartographer trophy, and it shows up in Fish Species and the Tank Builder right away.
- It's another name for a fish we already have. We add the name you used to that species (so searching it finds the right fish) instead of making a new page. Bubbles are only given when a new species is added.
- It's turned down. For example, if it isn't a freshwater species, or the name doesn't match a real animal. Our team can include a short note explaining why.
These notifications appear under the Trophies filter on your notifications page. See Notifications.
What do I earn for requesting a species?
When a species you requested is added to the library you earn:
- Bubbles, once per added request. See Bubbles.
- The Cartographer trophy (in the Library & Glossary section of your trophy cabinet). See Trophies.
You'll see a "You earned bubbles" notification, and if the bubbles move you into a new tier you'll also get a tier-up notification and email.
Can I request saltwater fish or plants?
The library is for freshwater aquarium species (fish, shrimp, snails and crayfish, with a few brackish species). Saltwater fish aren't part of it, so a request for one is likely to be turned down. Plants aren't in the species library either.
Who owns a species I suggest?
The Terms treat species suggestions like other library submissions: once we accept one for the library, it belongs to Underground Aquarium and we can use and change it as we choose. Suggestions we turn down stay yours.
Can I see or cancel my species requests?
There's no page listing your requests and no way to cancel or edit one after sending. If you made a mistake, send a corrected request with a note, or email support@undergroundaquarium.com.
Should I check before requesting a species?
Yes, it saves time. Before requesting:
- On Fish Species, make sure the group filter is set to All.
- Try the scientific name, other common names, or one distinctive word.
- For plecos, try the L-number with its leading zero, like L046.
See Searching the Fish Species directory for more search tips.
Common problems
The form says "Sign in to request a fish. You earn bubbles and a trophy when it's added." You're signed out. Tap Sign in, then open the form again.
"Enter the fish's name." The name box is empty or shorter than 3 characters. Type the name you know it by.
"Couldn't send that. Please try again." or another error. Check your connection and try again. If it keeps happening, email support@undergroundaquarium.com with the fish name.
The Send request button is grayed out. The form is still checking that you're signed in, or it's sending. Wait a moment.
I requested a fish but haven't heard back. Requests are reviewed by hand, so it can take a while. You'll get a notification when it's decided.
I didn't get bubbles for my request. Bubbles are only given when a new species is added. If your request turned out to be another name for a species we already had, or was turned down, there are no bubbles.
