Top 10 Non Aquatic Plants To Avoid In Fish Tank:

Keeping your aquatic plants healthy will help you get rid of toxic components that releases from fish waste. Plants are absorbers & they can absorb fish waste that can help them grow well. However, not every plant is suitable for aquarium especially if you want to fully submerge them. However, there is progress in growing more species of plants in aquarium that can survive in tank water. Hobbyists have more opportunities to choose aquatic plants for aquarium but in this article we are going to talk about plants that can’t live, grow slowly or die too early in aquariums.

Most of the aquarium & pet stores often sell non aquatic plants due to their high turnover. These plants will only stay alive for a short period of time in the aquarium & they will need to be replaced. After planting non aquatic plants, they will initially shoot new stems & grow new but the plant will eventually die after a few weeks or a month. You would be lucky to have them alive after couple of months of planting them in the fish tank. The reason is that these plants cannot tolerate too much water.
