Siamese Flying Fox Shark: A Lively Algae EaterShort Description: The Siamese Flying Fox Shark (Crossocheilus siamensis) is an energetic, peaceful algae eater perfect for community aquariums. It helps keep tanks clean while adding activity and charm.The Siamese Flying Fox Shark is a highly effective algae controller, bringing both form and function to freshwater aquariums. Native to Southeast Asia, it thrives in peaceful community tanks and is ideal for aquarists of all experience levels. Moreover, this active fish is known for its easy care, making it a favourite for those seeking both beauty and utility in their setup.Appearance and BehaviourThis striking species features a sleek, silver body highlighted by a bold horizontal black stripe. It can grow from 4 cm to a full adult size of 14 cm. With a streamlined shape and subtle golden shimmer, it glides through the lower levels of the tank. Additionally, its energetic swimming style adds constant movement, enhancing the visual appeal of any aquatic environment.Compatible Tank Mates for Algae-Eating SharksThese fish do well with peaceful, active companions such as tetras, rasboras, and guppies. However, it’s best to avoid slow or timid species, as the flying fox may be too lively for them. Keeping them in small groups encourages natural behaviour and reduces stress. As a result, your aquarium remains both clean and socially balanced.Feeding and Nutritional NeedsThe Siamese Flying Fox is not just an algae grazer—it enjoys a mixed diet. It readily eats algae off surfaces but also benefits from sinking flakes, blanched vegetables, and protein-rich treats like brine shrimp. Feeding twice a day ensures their nutritional needs are met and supports their role as natural tank cleaners. Therefore, variety is key to maintaining their health and energy levels.Breeding ChallengesBreeding this species in home aquariums is uncommon and typically requires advanced setups. A spacious tank with strong currents and thick vegetation is essential. After egg-laying, adults should be separated to protect the fry. With pristine water conditions and patience, success is possible. Thus, breeding is best attempted by experienced aquarists looking for a rewarding challenge.Species OverviewSpecies: Crossocheilus siamensisCommon Name: Siamese Flying Fox Shark (Real)Origin: AsiaDiet: OmnivorepH Range: 6.5 – 7.0Temperature: 26 – 28 °CBreed Type: Egg LayerCurrent Size: Approximately 4 cmMax Size: Approximately 14 cmSex: Un-sexedFAQsWhat tank size do they require?
