What are L-number catfishes?
It is not so dreadfully long ago that lori?cariid catfishes were regarded as the poor relations of the aquarium hobby, and were maintained and tolerated in the community aquarium solely on account of their often bizarre appearance and their useful characteristics.
Many of the most popular tropical aquarium fish kept today are more brightly colored than their wild relatives. Modern techniques have allowed the development of varieties to be taken to new extremes, with the first genetically modified fish now available.
