It is difficult to take care of the fish in the canvas pond. Ordinary fish tanks can be equipped with filters, or artificial water change, when changing water, water can be pumped from the bottom, and then poured from the tank wall, so that water quality and water temperature will not fluctuate greatly. If green algae grow in the tank, you can use the scraper to scrape the algae attached to the tank wall, but if green algae grow on the canvas, it is not so easy to clean up.
Canvas pond generally can only see the fish from the top, the other several directions are blocked by cloth, so viewing is somewhat inconvenient, and such a fish pond can not be placed too high, otherwise it is not convenient to overlook. The ordinary fish tank, in addition to the side against the wall can not see, other directions can be used to see the fish, multi-angle viewing can also appreciate the beauty of the fish.
Fish farming in canvas ponds Generally, goldfish or koi are raised. Because this kind of fish pond is not sealed, it is not easy to keep warm. It is basically impossible to raise tropical fish, and tropical fish are rarely viewed from the top down. Raising goldfish is better, after all, not big, if raising koi, there are certain requirements for the fish pond, the pond is too small to turn around, so the state of raising is not good.
