Luffy sent me these 4 marimos free in exchange for my honest review. Until the day I’d received these little moss balls I had never seen them in person. I thought they would be a perfect addition to my aquarium until I did some research. Apparently they like cool water, 70 and below, and also to be moved by gentle currents. That threw my aquarium idea out the window. I have tropical fish that like their water a little warmer. I have read conflicting anecdotal accounts about people using them in their tropical aquariums and not just with goldfish or bettas.
What I did was put the marimos in a decorative glass bowl and set them on the counter. The water needs to be changed at least once a week and the marimos need to be turned manually once a day or every other day so they continue to form in a round shape. One of the little guys looked like it was starting to split. I put it in a jar of cold water in the refrigerator to allow it some time to heal. Some people call this split a breeding ridge and I hope that is what it is and that it’s not damaged.
