The Ganges Delta is a river delta in the Bengal region of South Asia, consisting of Bangladesh and the Indian state of West Bengal. It is the world's largest river delta and it empties into the Bay of Bengal with the combined waters of several river systems, mainly those of the Brahmaputra river and the Ganges river. It is also one of the most fertile regions in the world, thus earning the nickname the Green Delta. The delta stretches from the Hooghly River east as far as the Meghna River. A delta is a triangular piece of land which develops at the mouth of a river by the deposition of Sediments.

The Burmese Border loach, angelicus loach or polka dot loach, Botia kubotai, is a recently described species that has quickly become a popular tropical fish for freshwater aquariums. In 2002, fish collectors working in western Thailand began to expand their search into Myanmar (Burma) area from the Three Pagodas Pass Thai-Myanmar border to look for new fish for the aquarium trade. This is one of several species discovered and explains the origin of the fish's common name: Burmese Border Loach. Its specific epithet honors Katsuma Kubota of an aquarium export company in Thailand who first purchased the catch and sent them out for identification.

The Ganges Basin is a part of the Ganges-Brahmaputra-Meghna (GBM) basin draining 1,086,000 square kilometres in Tibet, Nepal, India and Bangladesh. To the north, the Himalaya or lower parallel ranges beyond form the Ganges-Brahmaputra divide. On the west the Ganges Basin borders the Indus basin and then the Aravalli ridge. Southern limits are the Vindhyas and Chota Nagpur Plateau. On the east the Ganges merges with the Brahmaputra through a complex system of common distributaries into the Bay of Bengal. Its catchment lies in the states of Uttar Pradesh (294,364 km2), Madhya Pradesh (198,962 km2), Bihar (143,961 km2), Rajasthan (112,490 km2), West Bengal (71,485 km2), Haryana (34,341 km2), Himachal Pradesh (4,317 km2), Delhi, Arunachal Pradesh (1,484 km2), the whole of Bangladesh, Nepal and Bhutan. Several tributaries rise inside Tibet before flowing south through Nepal. The basin has a population of more than 500 million, making it the most populated river basin in the world.

Badis badis, also known as the blue perch or blue badis, is a small species of Asian freshwater fish in the family Badidae of the order Anabantiformes. It is found in ponds, rivers, ditches and swamps in northern India, eastern Pakistan, Bangladesh, Bhutan and Nepal, including the Ganges, Brahmaputra, Mahanadi and Indus basins.

Adult males have blue fins and may display dark vertical bands on the flanks, while the smaller females display little color. Several similar relatives, now recognized as separate Badis species, have historically been confused with Badis badis. Historically the two genera that now make up the Badidae, Badis and Dario, were placed in the family Nandidae; this is no longer the case.
Botiidae is a family of cypriniform ray-finned fishes from South, Southeast, and East Asia. Until recently they were placed in the true loach family Cobitidae, until Maurice Kottelat revised the loaches and re-elevated this taxon to family rank in 2012. The family includes about 56 species.
