It is simple and versatile,isn't it? I had cories spawn in java moss in another tank,just took the moss and plunked it in the marina box. No fungus,looked like 100% hatched.I do celestial pearl danios in a 15 gal. with a marina box hanging on. Once a week or so i take the java moss out of the 15 gal. and put it in the box, i usually get 10 -15 fry that way. I cut a small piece of sponge and put on the outflow of the marina.If you need java moss i could give you a nice clump, no problem. Thanks on the video/fish .
