The clown loach is a favorite species of fish for freshwater fishkeepers. It’s a pretty peaceful fish that can coexist with all other fish mates in the same tank. They’re also pretty amusing to look at because they’re very active during the day. The clown loach fish tends to feed on snails that can wind up in your fish tank.

This is a genus fish of cichlids native that features a distinctive, compressed body shape and it’s one of the best-looking freshwater aquarium fish that you can get buy because of the gorgeous bright colors that it has. These colors have granted the discus the title of “King of the Aquarium”.

With proper care and good feeding, the King of the Aquarium can have a very lengthy reign that spans between 10 and 18 years. It’s much easier to keep the captive-bred discus fish than their wild-caught ones because they don’t really require a pristine water quality to live in as much.

The discus fish can be spotted with a few blotches of yellow, black, and red pigmentations. Their anal and dorsal fins are rounded and have a pretty long base, while their pelvic fins are shaped almost like a saber. This fish can grow up to 9 inches and tend to weigh around half a pound.

Neon Tetra

It’s commonly known that the larger species of fish tend to live longer than the smaller ones, but the neon tetra is one of those small species that have a lifespan that rivals that of larger ones. It can live up to 5 to 10 years, which is around the same average lifespan of a goldfish.

Jack Dempsey

As the name suggests, this isn’t a very friendly aquarium fish and it’s certainly a bruiser. Named after the American boxer William Harrison, also known as Jack Dempsey, this fish has the looks that kill, literally. It’s nothing less than stunning but it’s fatal to a lot of other tank mates.

This species of fish is known to grow up to 8 to 9 inches in size and tend to have a lifespan of 10 to 15 years. Their sparkly bodies tend to have the colors cyan, blue, and gold very often. It’s too much for a lot of fishkeepers to care for the Jack Dempsey, but if you’re into predatory fish, then this is the fish for you.

When placed in fairly commodious fish tanks, the Jack Dempsey fish doesn’t show much of their aggression in small capacity tanks. However, it’s advised to keep this fish with other equal-sized cichlid fish such as the firemouth cichlid, green terror, blue acara, and the convict cichlid.

Final Words
