UPDATE: My betta's activity is back to 100%. He has built his first large bubble nest in over three weeks. His appetite is ferocious again. I feed him twice per day. The water has that nice, very light brown tint. Bettas do not live in crystal clear water. I want the best environment for my betta versus what some may view as cosmetically pleasing tohave crystal clear water. Additionally, he gets his flare on when I show him something he doesn't like. He even flared at a blue, ballpoint pin I was holding in front of his tank. I am very relieved to see him back in full form. I am very glad to have added this product to his tank. It may not have been the only thing that helped but it appears to have been very beneficial for him. Therefore I've added one additional star to this review. END UPDATE

Jury is still out as I do not see any coloration being added to the water. I broke a leaf in half (very large leaves) and placed both halves on opposite sides of my betta's 5.5 gallon tank. My betta uses one half as a blanket. He rests on top of his plastic leaf hammock completely covered by this product.

Prior to adding this product to his tank, he stopped eating for nearly two weeks. I grew concerned after the first few days of him not eating even though he was still fairly active. I turned his heater up from 78 degrees to 80 (it runs one half to one degree colder than the setting.I waited a few days and he still would not eat. I brought him a fresh can of betta flakes. He still would not eat. I offered him his favorite treat, blood worms. He still would not eat. I added Betta Fix and antibiotics to his tank. No change. I grewe very concerned.

I ordered this product after a week and a half of him not eating. My only comfort was he was still fairly active but I could see him slowing down a bit. I continued 25% water changes every few days. When the product arrived I immediately broke one leaf in half and placed them on opposite sides of the tank. Two or three days later my betta ate a small piece of flake food for the first time but left the rest. The next day he ate a little bit more than the previous time and left the rest, which gave me hope. Now he eats like the Tasmanian Devil, twice a day, just like he used to. He is fully active and making bubble nests again. I am so relieved.

I think I caused his issue. I started buying distilled water again for my tea (its been years). I used the distilled water to top off his tank a few times over the course of a week or two. I poured it right out of the plastic jug into his tank thinking distilled water must be okay. I suspect that caused a health issue and loss of appetite due to the timing of it. I am angry with myself for causing him a couple of weeks of distress. I should have known better.

Anyway, I don't know if his return to health was aided by this product or not. based on the timing it is possible this product played a role in my betta's recuperation. This is because I also added two live plants to his tank, which he loves. Two of the existing plants died a few weeks ago so I removed them and never replaced them, until now. I tried a few different things, which is the only reason I cannot definitely state this product helped to cure him. It may have. Based on the timing it is very possible.

The leaves for this product are very large and packed pretty flat (stacked on top of each other) in a sealed bag, but they were not crushed. They did a great job with the packing. I have only used one leaf thus far. I used a whole leaf in my 5.5 gallon tank because he was ill. I will have to read the label to see if I can reduce that to a half leaf for the 5.5 gallon tank in the future. I expected the water to tint as it does when I used Betta Spa (liquid). It may have tinted slightly and I do not notice as it may have been slight and gradual. In time I should be able to make a better judgement. For now, four stars seems like a fair rating for my experience. I may add or remove a star in the future. I currently lean toward adding a star versus removing one. We'll see.

I was really surprised at how quickly they arrived, and even more surprised just how big the leaves are! They really are giant and came completely whole in a sealed bag with the recommended amount of leaves to add per gallon which was extremely helpful. I'll definitely be buying from this seller again.

My bettas loved the Catappa leaves, they use them as hammocks and like hiding in them when they sink. I ordered them for my bettas since one is tail biting and I read that Catappa leaves help with fin growth. The shipping was super fast (they arrived within 2 days). Thank you! I would definitely recommend ordering from this seller.

These came better than expected! Packaged nicely and I had all full leaves. Very big size and worked wonders in my breeding tank. Gave our water a great color.

I recently received my package of Indian almond leaves for my betta fish. The leaves are large and provide a good sleeping place for my betta! So far, I like it and will continue to see how things go.

Edit* 7/26/2016 -- still love how my betta fish gets to blow bubbles under the leaf and lay on top of it as a hammock.
