Brochis agassizii
A small corydoras with rows of small brownish spots on a pale body. The first three dorsal-fin rays are black while the rest is whitish, and the species is notoriously hard to identify.
Brochis agassizii is a small callichthyid catfish from the Amazon basin near the border of Peru and Brazil, moved out of Corydoras agassizii in the 2024 generic revision. FishBase records 5.2cm standard length and Seriously Fish gives 70mm. Steindachner's original description notes that the first three dorsal-fin rays are completely black while the remainder is whitish with rows of small brownish spots, that the ventral fins are unmarked and yellowish, and that the caudal fin is bluish-white with three to five transverse rows of brown spots. Colour pattern is variable, however, and Seriously Fish states that the name is commonly misapplied to similar-looking fishes and that identification is difficult even when the collection locality is known. Aquarium conditions are 22-27C, pH 6.0-8.0 and 2-12dGH. It is peaceful and gregarious and should be kept in groups of at least four to six. The IUCN Red List assesses it as Least Concern.

Peaceful and gregarious; keep at least four to six. It mixes well with peaceful small and medium-sized fishes.
A foraging omnivore. Offer sinking dried food plus frozen bloodworm and Tubifex. It must never be expected to live on leftovers or to clean the tank.
Use two males per female. Once females are gravid, make a 50-70 percent water change with cooler water and raise oxygenation and flow. Eggs are laid on glass, fine-leaved plants or spawning mops.
Assessed Least Concern by the IUCN Red List. The name is commonly misapplied to similar-looking fishes, so a fish sold under it may not be this species. It is still traded under its former name Corydoras agassizii, so search under both scientific names. Apistogramma agassizii, a dwarf cichlid, is an entirely different fish.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
