Corydoras Tukano, a New Species of Corydoradine Catfish from the Rio Tiquié, Upper Rio Negro Basin, Brazil (Ostariophysi: Siluriformes: Callichthyidae)
Neotropical Ichthyology, 1(2):83-91, 2003 Copyright © 2003 Sociedade Brasileira de Ictiologia Corydoras tukano, a new species of corydoradine catfish from the rio Tiquié, upper rio Negro basin, Brazil (Ostariophysi: Siluriformes: Callichthyidae) Marcelo R. Britto* and Flávio C.T. Lima** A new Corydoras species from the rio Tiquié, upper rio Negro system, Amazonas, Brazil, is described. This taxon was previously referred to as “Corydoras species ‘Asher’”, “Corydoras cf. reynoldsi”, and “Corydoras aff. reynoldsi” in the aquarist literature. The new taxon can be distinguished from all its congeners, except Corydoras reynoldsi and C. weitzmani, by its color pattern, consisting of three large, dark blotches, the first one (“mask”) on the head, across the eye; the second one on the trunk at the level of dorsal fin; and the third one on the trunk at the level of the adipose fin. It can be distinguished from Corydoras reynoldsi mainly by the development of trunk blotches; and from C. weitzmani by the presence of a dusky saddle between the dorsal and adipose fins, the second trunk blotch extending vertically from the adipose-fin base to the anal-fin base, and the presence of four dark stripes in the caudal fin. Uma nova espécie de Corydoras do rio Tiquié, bacia do alto rio Negro, estado do Amazonas, Brasil, é descrita. Este táxon foi anteriormente citado na literatura aquarista como “Corydoras species ‘Asher’”, “Corydoras cf. reynoldsi” e “Corydoras aff. reynoldsi”. O novo táxon pode ser distinguido de todos seus congêneres, exceto Corydoras reynoldsi e C. weitzmani, por seu padrão de colorido, que consiste em três grandes manchas pretas, a primeira (“máscara”) na cabeça, através do olho; a segunda no tronco, no nível da nadadeira dorsal; e a terceira no tronco, no nível da nadadeira adiposa.

Fish Overview
The Toledo Zoo/ThinkingWorks Teacher Overview for the Fish Lessons Ó2003 Teacher Overview: Fish Fish have many traits that are unique to this particular class of animals. Below is a list of general fish traits to help you and your students complete the ThinkingWorks menu. This lesson focuses on typical fish that most people are familiar with, not on atypical fish such as seahorses. Fish are divided into three groups or classes, each with its own set of features. These classes include the bony fish (e.g., tuna and bass), cartilaginous fish (e.g., sharks and rays) and jawless fish (e.g., lampreys). We have included a list of the different fish found at The Toledo Zoo. Most of the fish are found in the Aquarium but there are also fish in the Diversity of Life. Note that animals move constantly in and out of the Zoo so the list below may be inaccurate. Please call the Zoo for a current list of fish that are on exhibit and their locations. Typical Fish Traits Lightweight, strong scales Lateral line for detecting for protection changes in turbulence along a fish as well as changes in water pressure Gas bladder for buoyancy, stability (internal) Symmetrical tail for Most fish have a well powerful swimming developed eye for locating prey, detecting predators and finding a mate. Flexible “lips” for picking up food Gills for extracting oxygen from the water Maneuverable, paired fins for Lightweight, strong moving forward and controlling skeleton for support roll, pitch and yaw q Fish are cold-blooded, obtaining heat from the surrounding water.

Adult Size: About 6 cm Minimum Tank Size: 18g Feeding: Flakes, Algae wafers and shrimp pellets, live food, frozen food, blanched vegetables. Spawning Method: Egg-layer Corydoras (AKA cory cats and cories) are very hardy and make good beginner fish for a community tank. For species tank, the dwarf cories do better. There are generally 2 types of cory, the dwarf cory and the normal cory. Brochis are not cories. The dwarf cory is great for nano tanks because it usually remains less than 3cm long ( about 1.3 inch). They do well in community tanks too and the only special care they require is not putting them together with aggressive fish like Cichlids. Dwarf Cichlids may do well with them occasionally but avoid them if you can.
