The assessment date reported by FishBase is February 25, 2011, so that status should not be presented as a newly updated evaluation. “Betta” also names a genus of many species, and their conservation categories differ.
Is the betta fish I see in pet stores endangered in the wild?
The common pet-store betta is usually Betta splendens, also called the Siamese fighting fish. FishBase reports its global IUCN Red List category as Vulnerable (VU), with an assessment dated February 25, 2011. Vulnerable is a formal category for wild extinction risk; it is not the same as Endangered. FishBase’s species record identifies the Red List data as part of its Version 2025-2 context, but the assessment date it reports is still 2011.
A newer global assessment for B. splendens has not been established here, so treat Vulnerable as the category in the located assessment, not a confirmed up-to-date status. The IUCN Red List is the reference for species’ global extinction-risk categories and related information such as range, habitat, threats, trade, and conservation measures.
Why are wild betta fish at risk?
For wild B. splendens, the cited threat review identifies habitat degradation and pollution. It describes suitable lowland habitat in central Thailand being converted to intensive farmland and urban areas. These pressures affect wild populations and habitat; they are distinct from the conditions in which captive aquarium fish are kept. The SEAFDEC-hosted review discusses these threats and the habitat conversion.

- Compact: Dimension: 7.9"x5.9"x5.9"; 1 Gallon tank; ideal for small spaces, aquarium beginners caring for a single betta, a few shrimp, snails, or a tiny goldfish. Also works as a temporary hospital tank, quarantine tank, or desktop decor (After deducting the filter part, the actual usable volume is approximately 0.8 gal and it will further decrease after adding substrate)
- Customizable Lighting: features a 3-color LED hood with 10 adjustable brightness levels to showcase your fish and tank décor
- Self-Cleaning Filtration: Hidden filter keeps tank clean for easier maintenance. Note: Clean filter sponge and pump regularly to avoid clogging; regular water changes are required — this small tank does not support zero-maintenance use
- Thoughtful Design: its top feeding hole allows for easy feeding without removing the lid; four silicone feet for stability and quiet operation
- Complete Starter Kit: 1x 1 gallon Fish Tank, 1x Filter Sponge, 1x Adjustable Water Pump, 1x LED Hood (Note: The light requires a power transformer (not included) for use. Compatible transformers include 5V 0.5A, 5V 1A, 5V 1.5A, and 5V 2A)
The available material does not quantify the relative contribution of habitat loss, pollution, or trade pressure to the species’ risk. It also does not establish a population total, a measured decline percentage, or a current habitat-area estimate, so those figures should not be inferred.
Are all betta species endangered?
No. Each species has its own assessment, and the examples below show why a genus-wide label is misleading.

| Betta splendens | Vulnerable (VU), as reported by FishBase | February 25, 2011 |
| Betta tomi | Endangered | January 5, 2019 |
| Betta pugnax | Least Concern | January 18, 2019 |
The two 2019 examples are listed on the IUCN Red List pages for Betta tomi and Betta pugnax. Their categories apply to those named species, not automatically to every betta.

No. A species can be widespread in the aquarium trade while its wild populations face conservation risks. The number of captive fish available does not, by itself, show the condition of populations in their native range.

There is also a separate question about what happens if aquarium fish are introduced outside their native range. The US Fish and Wildlife Service describes B. splendens as ubiquitous in the aquarium trade, but its ecological risk screening for introductions in the contiguous United States is uncertain because more information is needed. That screening concerns potential ecological risk in the United States, not global extinction risk in the species’ native range. The FWS ecological risk screening summary addresses that distinct question.
