Ecology of Horaglanis krishnai
 
Main Ref. Proudlove, G.S., 1997
Remarks Inhabits the dug-out wells at Kottayam, Kerala. It has unusual habitat in freshwater wells to which they gain entry through the subsoil drainage system (Ref. 57760). The short intestine appears to indicate that this fish is carnivore. The gut showed the presence of insects (Ref. 57760).
