A peaceful, schooling catfish ideally suited to soft water communities containing tetras, rasboras. These fish breeds are native to inland waters in South America. This fact was also evidenced when using other banding techniques, such as RE (AluI), and indicates that this pair constitutes a species-specific cytogenetic marker. Dianema urostriatum (Flag-Tailed Porthole Catfish). Porthole Catfish is a variety of freshwater fish that comes from the Callichthyinae family. C-banding revealed a small amount of heterochromatin in chromosomes, including the NORs, and one biarmed pair that showed conspicuous positive bands on both arms. NORs detected by AgNO₃ were located in the terminal regions of the short arm of a st chromosome pair, as confirmed by CMA₃ and FISH using an 18S rDNA probe. As for your Corydoras and Porthole Catfish, they will probably be alright providing the aquarium has plenty of. The karyotype shows a diploid number of 2n=56 chromosomes comprising 22m, 16sm, 10st, 8a (FN=104). A unique armored catfish and a favorite in the aquarium hobby for decades, the flagtail porthole catfish is distinguished by its unique black and white. In this work, Hemisorubim platyrhynchos from three isolated populations were cytogenetically analyzed. 103-110 ISSN: 1993-078X Subject: Hemisorubim platyrhynchos, Neotropics, catfish, chromosome banding, diploidy, fisheries, heterochromatin, karyotyping, rivers Abstract: Hemisorubim platyrhynchos is a medium- to large-sized pimelodid catfish distributed along several river basins of the Neotropical Region, noteworthy for representing an important fishery source. It natively inhabits waters with a pH range of 5. The fish will grow in length up to 8.2 centimetres (3.2 in).
