Mastering Green Chromide (Etroplus suratensis) Aquariums: Care, 10 Best Tank Mates, and FAQs

The Green Chromide, scientifically known as Etroplus suratensis, is a fascinating fish that calls the brackish waters of India and Sri Lanka home. This oval-shaped swimmer, with its greenish-gray body adorned with dark stripes, is a sight to behold. Belonging to the cichlid family, it shares kinship with other popular aquarium fish like angelfish and discus.

What makes the Green Chromide truly special is its ability to thrive in both fresh and saltwater environments. Imagine a fish that can swim from rivers to coastal lagoons without missing a beat! This adaptability has earned it the nickname “pearlspot” due to the pearly white spots that shimmer on its scales.

The scientific name Etroplus suratensis has an interesting story. “Etroplus” comes from Greek words meaning “belly” and “arms,” referring to the fish’s long spiny anal fin. “Suratensis” points to Surat, a city in India where the fish was first described.

In the wild, these fish are bottom-dwellers, happily munching on algae, small insects, and plant matter. They’re social creatures, often seen swimming in groups. But don’t let their peaceful nature fool you – they can be quite territorial when it comes to breeding time!

Speaking of breeding, Green Chromides are devoted parents. Both mom and dad work together to care for their eggs and fry. They even produce a special mucus that serves as the first meal for their babies. Talk about a nutritious breakfast!

A study published in the Journal of Fish Biology revealed something fascinating about these fish. Researchers found that Green Chromides in Singapore have adapted to living in completely freshwater habitats, challenging the belief that they always need salt in their water.

Fun fact: In Kerala, India, the Green Chromide is so beloved that it was named the official state fish in 2010. The following year was even declared “The Year of the Karimeen” (another local name for the fish).

From ancient lagoons to modern aquariums, the Green Chromide has swum its way into the hearts of fish enthusiasts worldwide. Its ability to adapt, its striking appearance, and its interesting behaviors make it a true gem in the underwater world.

Green Chromide Key Information

The Green Chromide, a stunning fish with a captivating appearance, boasts a greenish-gray body adorned with dark vertical stripes.
