The guppies like the still water best, followed by the smaller water flow. Because they are small fish, many small fish prefer to live in still water. Because of their small size and weak swimming ability, they can't resist too much water flow under normal circumstances. If the breeder keeps the guppy in a fish tank with a large current, the impact of the current will make the guppy unable to move normally, and may make their body unable to maintain balance.
In addition, their fins need to swing constantly in the environment with large current. But when they are resting, the fins will stop swinging. If the current is too large, they will be washed away by the current when resting, which will seriously affect the rest of guppies.
2. Do guppies like acidic water or alkaline waterAlkaline water is the favorite of guppies, and the most suitable PH value for their growth is between 7.2 and 7.4. When breeding guppy, it is best to check the pH value of water frequently. If the water quality is acidic, the breeder needs to adjust immediately. It is best to check the water quality before changing water every time. When the water is acidic, breeders can add some quicklime, baking soda, big soda, etc. These substances are weakly alkaline. Compared with lime water, big soda and baking soda are milder, and big soda can also eliminate chlorine in water, which is very suitable for guppy.
