Siamese Algae Eater

Regular price $ 6.99

The Siamese Algae Eater (Crossocheilus oblongus) is a great addition to any community tank. Originating from Thailand, Laos, and Cambodia, these fish are renowned for their algae-eating capabilities and also thrive in streams and rivers with abundant vegetation. In aquariums, Siamese Algae Eaters often graze on hair algae and also perch on decor.

Moreover, while hair algae can be a significant part of their diet, they also consume flakes, pellets, and algae wafers, ensuring they remain healthy and active. They can be kept singly or in groups and are generally peaceful, coexisting well with other fish species. Typically reaching up to 6 inches, however with most around 4 inches, they are suitable for various tank setups.

Available Sizes: 

  • Regular
  • XL - Get these larger fish that are already close to 4 inches long. Limited availability!

Dead fish

Love the fish but the service is horrible, had 2 dead glow fish and 1 dead algae eater upon arrival, every time we called it said closed and that was during business hours. Even left multiple messages and no return calls.
