The vast majority of lampreys come from the territory of Thailand, Malaysia, Indonesia and other countries in Southeast Asia, as well as the Amazon River Basin in South America along the freshwater fish. Affected by the local climate, lampreys generally like acidic soft water, PH value of about 6 to 7, hardness of about 1.

Compared to some other costly saltwater fish, the water temperature and pH requirements are exceptionally strict, in the lamprey how to raise this aspect, the lamprey is considered to be quite a well-fed ornamental fish. The lamprey's requirement for water temperature is about 22~28℃, and when the temperature rises in summer you can use a water cooler to cool it down, and in winter you can use a heating rod to warm it up, in order to maintain a suitable environment for the lamprey's healthy growth.

The water cooler and heating rods used for keeping lampreys are not expensive among the many equipment for ornamental fish, and can be used for a long time. In terms of food, you can usually feed artificial feed and active bait.

Artificial feeds, such as flake feeds, can be a good solution to the phenomenon that some lampreys don't eat sinking bait, and they are easy to carry, clean, and convenient to feed. In addition to artificial feeds, most lamprey species favor active baits because they are closer to their predatory nature and are nutritious and healthy.

However, active bait is not as clean and hygienic as artificial feed, which is disliked by many breeders, so you can use frozen active bait, such as frozen red worms, frozen shrimp and other frozen bait. Compared to other large ornamental fish, lampreys tend to require a very simple diet, which is small and very cheap.
