It is best to use naked tank feeding. Because the bottom sand is laid at the bottom of the fish tank, the water below is not always flowing. Over time, the water quality will deteriorate. In addition, fish feces will fall inside and adhere to the bottom sand, which is difficult to clean up. Long-term accumulation of feces in water will not only have a negative impact on water quality, but also breed bacteria. If it is not cleaned up in time, it will easily lead to fish illness.
If the tank space is not enough, or there is no filtration system, it is not recommended to put bottom sand in the tank. However, when raised in a bare tank, daily care becomes very simple. As long as the water is changed regularly, the environment in the fish tank can be kept clean without worrying about the deterioration of water quality.
If you want to put bottom sand in the fish tank, you must ensure that the bottom sand is clean, non-toxic and harmless. The adaptability of guppy is very strong, so it does not require high varieties of bottom sand. Neutral bottom sand, such as black gold sand, Dutch sand and river sand, can be used as bottom sand for breeding. You can also use coral sand, which makes the water alkaline. Let the fish live in an alkaline environment, which is more conducive to its growth. However, it should be noted that the bottom sand in the fish tank should be cleaned regularly, otherwise it will affect the water quality.
