What I like about this substrate so far is that the eggs are spaced evenly, which is very important for their development. The plant's leaves are spread out in all directions exposing eggs to a good water circulation and supply of oxygen. This "mops" will be very easy to remove after the eggs hatch without sacrificing any fry. Lastly this medium doesn't seems to be catching any derbies. The ranchu seems to like my spawning "forest" too.
