Cory Catfish

Cory catfish are algae eaters. So, they will eat the algae off the sides of the tank and the plants. They spend most of their time scavenging at the bottom of the tank.

Iridescent Shark

Iridescent sharks are a species of catfish native to Asia. While they are excellent tank fish, you must remember that they will eat any fish that can fit into their mouth. So, fish like Tetras, Danios, and Barbs are not good mates for tanks with iridescent sharks. They also need at least a 300-gallon tank.

Betta Fish

The Siamese fighting fish, also known as the betta, is popular in the aquarium trade. Bettas in the wild are carnivores. So, they feed on carrion, shrimp, insect larvae, insects, and small worms. These types of tropical fish, if kept as a pet, prefer solitary. But, there are some types of snails (aquarium snails) that you can add to the tank without issue.
