Relevant Information:

Can sometimes be difficult to identify, has two white stripes along the body with a blackish stripe splitting them. All fins have a yellow tinge. Lineage: Placed in Lineage 5 and a revision and the resurrection of the genus name Gastrodermus Cope, 1878 has now finely occurred (2024). Aquarium Care: This is akin to most of this genus, very peaceful, and would be best housed with small to medium sized tankmates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Best to purchase 6 individuals or more as they will be happier in a group. Diet: Readily accepts a mixed and varied diet which includes granular foods, tablet food, frozen bloodworm and a good quality flake. Etymology: The genus name Gastrodermus: The lining membrane of the alimentary tract of an invertebrate, used especially when the germ-layer origin is obscure. The specific name bilineatus: Meaning with two lines. Remarks: Still found on some online sources as Corydoras bilineatus.
