Rubiesichthys

Rubiesichthys is a small nektonic milkfish cousin of Chanidae found in the Mediterranean Seas during the Early Cretaceous and found in Lerina, Spain. It has a longer body, a petite size, short fin limbs, and a forked tail.

Both morphotypes are discriminated by their relative body height only and do not differ in any other morphometric, meristic, or anatomic character. They both occur at the same levels in the same localities, in about a 50–50% ratio for adult individuals, and there is no difference between the morphotypes and specimens from both known populations, El Montsec and Las Hoyas. Consequently, the two morphotypes of Rubiesichthys are interpreted as sexual dimorphs.

Rubiesichthys was first described at site along with small teleostean fishes from the Early Cretaceous of El Montsec, Lérida, Spain. It was found only at Las Hoyas Formation.

Tamed

Rubiesichthys can be 'tamed' using Fish Trapper. While they can level, they do eat from the feeder.

The holotype of Rubiesichthys gregalis is kept at the Institut de Paleontologia “Miquel Crusafont," Sabadell, Barcelona, Spain (IPMC). (IPS, Institut de Paleontologia de Sabadell). Other specimens of Rubiesichthys from Montsec are kept in the collections of the Museu de Geologia, Barcelona, Spain (MGB), the Museu del Seminari, Barcelona, Spain (MS), and The Natural History Museum, London, United Kingdom (NHM). Some specimens of Rubiesichthys from Las Hoyas are from the private collection of Mr. Armando DÍAZ ROMERAL (Cuenca,Spain) (ADR); the rest belong to the Museo de Cuenca, Spain, and are provisionally housed at the Unidad de Paleontología de la Universidad Autónoma de Madrid (UAM).
