Often sold in your LFS as T. decaradiatus but this species is not seen often in the hobby as exports from the Guyana area are rarely heard of. To see the differences in both species our factsheet will explain more about the shape of the humeral process and the eye position. Aquarium Care: Keeping both species is not too much of a problem as long as the water is kept clean and not too alkaline with a p.H.of between 6.5 and 7.0. They do like a planted aquarium where they like to hide out during the day. Diet: In the aquarium a good mixture of dry food such as flake and tablet. Worm food such as bloodworm, whiteworm and grindal. Etymology: Trachelyichthys: trachely, referring to close similarity to and relationship with Trachelyopterus; ichthys; fish. The specific name exilis: slim or slender, pertaining to the slim humeral process.
