Review: Worked super well!! - I’ve seen a lot of reviews saying it looks like a teddy bears tail was cut off, but obviously this isn’t real moss. Others say it floats and I have to agree it doesn’t just sink right away, however if you hold it under water and move it around you’ll start to see bubbles and it’ll eventually sink. Patience is key! As far as replicating a moss ball it looks very nice and high quality in my Bettas 9 gallon tank and ended up sitting perfectly on the wood piece decor as shown. Lately the tanks water had been cloudy and I tried everything from water clarifiers to bio capsule water cleaners and non of those worked! I put the moss ball in the tank a few days ago and within 4 days, the water cleared up noticeably better to the point it looked like I had just cleaned it and put fresh water in. Also the smell of fish water has almost entirely gone away too unless I’m standing directly over it. The fact these can stay in for months and help keep the water clear makes this highly worth the money for anybody looking for a moss ball either for decor or for keeping the water clear.
Review: Great for turtle habitat - Size is accurate to the product description. These are super soft high quality moss balls. My turtle loves them, and I love that her tank looks so nice! They’re holding up after several months, and are absolutely worth the money. Great product.
