Give a no-stress home to your betta --- When fish are given their native ambiance, they tend to grow stronger and heartier. By balancing the pH level, our leaves provide ideal water conditions. The Indian Almond leaves are considered to have beneficial properties and increase fish appetite making them happy.

Have a breeding pet? Add catappa --- The tropical fishes create bubble nests using a floating leaf or a plant to anchor their bubbles. So if your tank has any one of the breeding tropical fish like tetra, guppy, platies, molly, cichlids, just add these leaves and see them anchoring their eggs over IAL. That is a sight to behold. In ancient times, the Ketapang leaves were used in folk medicine for indigestion.

Benefits other fish and snails too --- The tea water has many advantages for fishes like tetra, discus, and goldfish. It is good for rasporas and many dwarf cichlids too. Apart from that, snail owners can benefit from the magical leaves. Giving your fish such an ambiance calms them down and aids in overall development. It helps in imparting color to them and makes their scales firmer.
