Cichlasomatini Fish Tribe Explained

The Cichlasomatini fish tribe is a fascinating group of species. They are a subgroup of the cichlid family, which is one of the largest and most diverse groups of fish in the world.

One of the defining characteristics of the Cichlasomatini tribe is their small to medium size, typically ranging from 2 to 10 inches in length. This makes them a popular choice for aquarium hobbyists.

These fish are native to Central and South America, with a range that spans from Mexico to Argentina. They inhabit a variety of freshwater environments, including rivers, lakes, and wetlands.

Mercury chloride has been found to have genotoxic effects on the neotropical fish Andinoacara rivulatus.

This means that exposure to mercury chloride can cause damage to the DNA of this species of fish.

Research has shown that mercury chloride can lead to erythrocyte nuclear abnormalities in Andinoacara rivulatus.

The formation of micronuclei is also a consequence of mercury chloride exposure in this fish species.

The effects of mercury chloride on Andinoacara rivulatus have been studied extensively by researchers at the Universidade Estadual Paulista (UNESP).

A study published in 2019 examined the genotoxic effects of mercury chloride on this species of fish.

The study found that mercury chloride can cause significant damage to the DNA of Andinoacara rivulatus.

This research highlights the importance of monitoring and regulating the levels of mercury chloride in aquatic environments where this species of fish is found.

Here are some key findings from the study:

Taxonomy of Cichlasomatini is quite complex, with three Untertriben (subclades) identified.

The Cichlasomatini tribe is divided into three Untertriben: Cichlasomatina, Nannacarina, and Andinoacarina.

Cichlasomatina Untertribe includes the genus Cichlasoma, which is home to many species.

Aequidens and Krobia are also part of the Cichlasomatina Untertribe.

Nannacarina Untertribe includes the genus Nannacara and Ivanacara, which are closely related.

Cleithracara is another genus within the Nannacarina Untertribe.

Acaronia is a genus within the Nannacarina Untertribe, and it includes the species Laetacara and Rondonacara.

The Andinoacarina Untertribe is home to the genus Tahuantinsuyoa and Bujurquina.

Andinoacara is also part of the Andinoacarina Untertribe.

There are 170 described species within the Cichlasomatini tribe, with some unclassified species still awaiting discovery.

The Cichlasomatini are a group of fish that are surprisingly similar to each other despite their varying appearances. They are all characterized by being side-flattened, high-backed, and only slightly stretched in shape, which is pretty typical for cichlids.

Their physical characteristics are not super distinctive, but one notable feature is the size of their scales - they're relatively large. You might notice that the scales before the dorsal fin are arranged in a specific way, with eight scales on the middle line instead of more than ten.

Cichlasomatini are all substrate spawners, which means they lay their eggs on the substrate rather than in a nest. This is a pretty common trait among cichlids, but it's worth noting if you're interested in breeding them.
