Aquatic Curiosities: Fascinating Facts About Fish and Aquarium Life

In nano community aquariums, the Clown Killifish often coexists well with calm bottom dwellers like the Pygmy Corydoras, as they occupy entirely different water levels and rarely interact.

The surface-oriented lifestyle of the Clown Killifish makes it vulnerable to competition from faster fish such as the Endler Guppy, which can outcompete it for floating food.

The Clown Killifish is biologically adapted to live almost exclusively at the water surface, using its upturned mouth to capture tiny insects and larvae.

Bushymouth Catfish coexists well with calm species like Angelfish, as it occupies lower tank zones and avoids direct competition for food.

During reproduction, the male Bushymouth Catfish guards eggs laid inside caves, aggressively defending them from intruders including other bottom dwellers such as Corydoras Catfish.

Bushymouth Catfish has a suction-cup mouth adapted for scraping algae and biofilm, often reducing competition with mid-water feeders like Neon Tetra.

Male Bushymouth Catfish develop prominent bristle-like tentacles on their snouts, which are believed to play a role in sexual selection and territory signaling.

The Bronze Corydoras is known to form mixed schools with the Panda Cory, displaying cooperative foraging behavior across species.

In the wild and in aquariums, the Bronze Corydoras often schools beneath groups of Neon Tetra, benefiting from shared safety in numbers.

The Bronze Corydoras can gulp air from the surface and absorb oxygen through its intestine, an adaptation shared with several Corydoras species living in low-oxygen waters.

The Bronze Corydoras has been kept by aquarists for over a century, making it one of the earliest South American catfish introduced to the hobby.

Most Red Neon Blue-eye found in the aquarium trade today are captive-bred, reducing collection pressure on wild populations and supporting long-term conservation.
