It is best to raise guppy without bottom sand, because bottom sand is laid at the bottom of fish tank, although it will not have a direct impact on guppy. However, the food residue and feces of guppy will fall into it, and the bottom sand is easy to hide bacteria. If it is not cleaned for a long time, it is easy to pollute the water quality. Moreover, guppies don't like too much water flow. Under normal circumstances, the filter installed by breeders is not very powerful, so it is difficult to clean up the impurities in the bottom sand. Therefore, under normal circumstances, it is best for breeders not to lay bottom sand for guppies. If the bottom sand is not laid, as long as the water is changed regularly, the water quality can be guaranteed to be clean.

It is best not to plant aquatic plants for guppy breeders. Because aquatic plants easily lead to weakly acidic water quality, and the water quality suitable for guppy growth is weakly alkaline, if too many aquatic plants are planted, their normal development may be affected. In addition, planting aquatic plants requires laying bottom sand or aquatic plant mud, which is easy to breed bacteria. If there is no powerful filtration system, it is best not to plant aquatic plants.

In addition, the space required by aquatic plants is relatively large. If too many aquatic plants are planted, the growth activities of guppy will be limited, so try not to plant aquatic plants when the space is not very sufficient.
