Ticto barb
Freshwater and brackish subtropical fish
The ticto barb or twospot barb (Pethia ticto) is a species of subtropical freshwater fish belonging to the family Cyprinidae. It is a native of the upper Mekong, Salwen, Irrawaddy, Meklong and upper Charo Phraya basins in the countries of Nepal, India, Pakistan, Myanmar, Bangladesh, Thailand, and Sri Lanka. It has frequently been confused with the Odessa barb in the aquarium trade, but in that species the male is reddish-orange (lacking in P. ticto).
The ticto barb is silver and gold with two black spots; one just before the pectoral fin and one near the back tail. It grows to a maximum length of 10 cm (4 in).
It is natively found in still, shallow, marginal waters of lakes and rivers, usually with muddy bottoms. It browses close to the substrate in shallow water. Ticto barbs natively live in a subtropical environment and prefer water with a 6.0—7.0 pH, a water hardness of up to 10 dGH, and a temperature range of 14–22 °C (57–72 °F). Their diet consists of small crustaceans, insects and plankton.
The ticto barb is one of many barbs undergoing revisions in their taxonomic classification.
Begin with the source’s own compact description: “Ticto barb” is freshwater and brackish subtropical fish. The dossier treats that line as a proposition to test through Ticto, barb and Freshwater, not as a finished interpretation.
Why this record matters
The phrase “freshwater and brackish subtropical fish” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 4, 2026. The linked authority identifier is Q233025. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
