usually clean fish can play a role in improving water quality, such as scavenger, black line flying fox, golden moss rat, elf fish and black Mary, etc. Scavenger is the most common tool fish, generally used to clean up the bottom of the tank of residual bait and fish feces, although it can be effective in a short time, but after its excretion, the water quality will deteriorate, so other methods are needed. Black line flying fox, golden moss rat, elf fish and black Mary are all algae eaters. Although they can't clean up the bottom of the water, they can eat algae and avoid the occurrence of algae explosion.
water quality? 1. Grass goldfish: Grass goldfish is the most common and oldest kind of goldfish, so it has strong adaptability and low water quality requirements, and is very easy to raise. Moreover, as a wide temperature fish, it does not need to be equipped with heating rods, oxygen pumps and other equipment, which is more suitable for novices.
2. Manlongyu: Manlongyu is a small tropical ornamental fish. It not only does not require high water quality, but also tolerates low oxygen environment. This is because it is a fish of the gourami family, which has an auxiliary respiratory organ that allows it to float to the surface to breathe when dissolved oxygen is low.
3, zebrafish: zebrafish is very small, relatively mild temperament, and will swim all day, relatively easy to raise, but also very suitable for polyculture. Although it is a tropical fish, it has a strong adaptability to water temperature, can survive in the environment of 11-15 C, and does not require high water quality.
