The zebra loach, Botia striata, is a botiid loach from the Krishna River system in southern India, described from the Tunga River in Karnataka. Its yellow to golden body with blue, green, grey or black bars and typically red mouthparts make it one of the most easily recognised in the genus, although the bars break up entirely in some specimens. Given its adult size and peaceable nature it is perhaps the best choice of Botia for the general community.

The dwarf snakehead, Channa gachua, is a snakehead recorded across an enormous range from Iran to Taiwan and Bali. There is significant evidence that C. gachua as currently understood is a complex of similar-looking species in need of taxonomic review. A mouthbrooder bred regularly in captivity, it can share a well-chosen community with peaceful fishes too large to be prey, but populations should not be mixed as some may hybridise.
