Lambchop Rasbora

Description

Trigonostigma espei

Varies with locality. It most commonly inhabits gently flowing sections of forest streams and tributaries where submergedaquaticplants grow thickly. The water is sometimes stained faintly brown/yellow due to the presence of tannins and other chemicals released by decomposingorganicmatter and thesubstratescattered with fallen leaves, twigs and branches.

Such environments characteristically contain soft, weaklyacidictoneutral waterand are often dimly-lit due to densemarginalvegetation and the forest canopy above.

In Krabi province, southern Thailand it can be found living in a particular karstic (limestone) area withneutraltoalkalinewater (pH7.0-7.4). Thehabitatconsists of a series of deep limestone sinkholes forming pools at the surface, plus a small ditch which acts as an overflow from the pools.
