The tiger grunter (Amniataba affinis) is a freshwater species of ray-finned fish within the family Terapontidae.

[1] Tiger grunter adults live a demersal lifestyle in tropical swampy lagoons, backwaters and main channels of turbid rivers.

[1] The tiger grunter faces threats such as commercial development, fishing, invasive species (Such as tilapia, snakeheads, rusa deer and common water hycinth), droughts, fires, mining and pollution.

No current conservation efforts have been made so far, although its range in the Bensbach River overlaps with the Tonda Wildlife Management protected area.

The tiger grunter has been classified as 'Least concern' by the IUCN Red List, and more research is required to fully determine its current population and impact from threats.
