Outstanding

Main highlights

•Give a peaceful home to your betta --- When fish are given a homely ambiance, they tend to grow stronger. By creating ideal water conditions, we assure that they can prosper. The Indian Almond leaves are considered to have beneficial properties and increase fish appetite.
•Have a breeding pet? Add catappa --- The tropical fishes create bubble nests using a floating leaf to anchor their bubbles. So, if your tank has a breeding tetra, guppy, platies, molly, cichlid or shrimps, just add these leaves and see them anchoring their eggs over IAL. That is a sight to behold.
•Benefits other fish and snails too --- The tea water has many advantages for fishes like tetra, discus, and goldfish. It is good for rasboras and many dwarf cichlids too. Apart from that, snail owners can benefit from the magical leaves. Giving your fish this ambience calms them down. It imparts color to them and makes their scales firmer.
•Smaller leaves, easier portion control --- Each packet contains 50 leaves measuring around 2-inches high which is a great value for money. Smaller Catappa leaves make for easier portion control and a good way to slowly introduce your pet to a new surrounding especially for smaller fishes in smaller tanks.
•Adds beauty to nano tanks, small bowls and jars --- The Catappa leaves from SunGrow are unprocessed so you know what goes into your tank. They look pretty in a nano tank and add aesthetic beauty to your planted tank. You may even add these in individual betta jars or bowls.
