Cory Catfish

Native to South America, Cory catfish are one of the most popular bottom-dwelling scavengers for freshwater aquariums. They thrive in a wide range of water conditions and stay relatively small makes them perfect for a smaller community you’re running!

Cory Catfish can be active during the daytime hours, and they are most active at dawn and dusk. Sometimes, they are often seen resting motionless in a single spot for hours.

Cory catfish, like all catfish, spend most of their time at the bottom of the aquarium to find food, which can help keep your tank clean. Keep these creatures happy by having a soft sand substrate on the bottom to provide them with their natural habitat and plenty of room for exploring!

Buenos Aires Tetras

Buenos Aires Tetra

The Buenos Aires Tetra is hardiness and ease of care that make it very popular. The fish derives its name from the capital city of Argentina. You can find them in rivers, streams, and lakes branching out into the Río de la Plata, located on the southeastern coast of South America.

A Buenos Aires Tetra’s unique coloration is what sets them apart from other types of tetras. It has a slender silver body, red fins with a thin blue stripe that extends from behind the gill plate and ends at the tail fin. When light hits this stripe, it will appear as though they are shimmering in every color imaginable! One of the most popular varieties, Albino Buenos Aires Tetra, has been bred with a yellow tail. They are amazing and fun to watch. 

Buenos Aires Tetras are active schooling fish. They crave safety in numbers, so a group of six or more fish of the same species is highly suggested. 

Probably the essential part of caring for your Buenos Aires Tetras is replicating the water temperatures of their natural habitat in Argentina. You should keep them in a clean environment with regular water changes. This way, the fish is less likely to suffer from nitrates and phosphates as well as high levels of hardness due to evaporation.

Pro tip: Don't keep Buenos Aires Tetras in live planted tanks because they will eat most live plants. I strongly recommend using artificial plastic plants instead, or sturdy plants such as Java fern.

Congo Tetra

Congo Tetra

The Congo Tetra is considered by many aquarists as the jewel of tetras no matter you’re a beginner or an expert looking for a pretty beautiful addition to the home aquarium. 

Congo Tetras are a species of fish in the African tetra family that are shaped like typical tetra. They have large scales on their bodies which make them appear more compressed than other fishes. When they get older, this iridescent fish boasts a captivating rainbow appearance. When fully matured, these iridescent scales provide an almost magical color spectrum that shifts between blue and gold to violet or turquoise depending on where light reflects off their bodies. 

Pro tip: You should never keep congo tetras with any species with a penchant for nipping fins because the males' spectacular fin will be destroyed. They also shouldn't be kept with boisterous tankmates, as they are shy fish and not suited to such environments.

If that wasn’t enough, Congo Tetras are easy to care for, but only if provided with the correct habitats and water conditions.
