These are not only decorative but are useful in spawning situations. If angelfish lay eggs on a leaf, just remove it and hatch the eggs artificially. After they hatch you can put the leaf back on the stem. We use them most often in livebearer tanks. We let them float in a bunch and the new-born fry find it great to hide in. This is why we've chosen to carry fine-leaf plants.
