Lebiasinids are small, cylindrical fish, ranging from 2 to 18 cm (0.8 to 7.1 in) in adult length. They prey on insect larvae, especially those of mosquitos. The family includes the voladoras (genera Lebiasina and Piabucina), mostly found in highlands of the north Andes, the Guiana Shield and Central America, but the other species are mainly lowland fish inhabiting the Orinoco, Amazon and Paraguay River basins, and rivers of the Guianas.[1]

gollark: A simple if slightly inaccurate way would be some kind of binary space partitioning thing, where (pretending the US is a perfect square) you just repeatedly divide it in half (alternatingly vertically/horizontally), but stop dividing a particular subregion when population goes below some target number.
gollark: The more complex the algorithm the more people might try and manipulate it. The obvious* solution is to just split up the country by latitude/longitude grid squares.
gollark: The Netherlands will just conquer all of the areas "lost" to rising sea levels.

gollark: Using more/better technology generally requires more electricity.
