Name: Anubias nana|
Origin: West Africa|
The Dwarf Anubias is definitely a cast-iron plant. This plant is so hardy that it can even survive out of water. In fact, the only other plant hardier than the anubias is algae. It needs very little light and isn't fussy about water conditions. The only drawbacks are that they grow quite slowly and are vulnerable to beard algae. Like all Anubias species, they are grown from a rhizome and they should be tied to rocks or driftwood. They will also grow well if placed on the gravel. This means that they like water flowing around their rhizome. The Dwarf Anubias will be a great addition to any planted aquarium.
Nice plants, that I grow both in my 200 L planted with extra light, CO2 and fertilizer, and in my 110 L tall with 20 W bulb, no CO2 and no fertilizer other than fish. The two I have in my 200 L grow about twice as fast (1-2 new leaves a week!) as the one I have in my 110 L, but all are growing quite well.
This is hands-down the favorite of my plants! I have mine attached to driftwood, and rocks, and even have some in the substrate, with the rhizomes above the substrate. They do grow slowly, but their thick leaves are unpalatable to most fish, and I find that none of my fish are interested in eating them. Because they do not need to be "rooted" in the soil, they make for easy "replantings" should you feel the need to rearrange your plants and change your display. They aren't fussy, they do well in a wide range of water parameters, do not need much light, and sprout new leaves at least every 2 weeks, if not more frequently. They are slow growers, as far as height, though. The leaves are long-lasting, and if they should get algae, Otos and SAEs can take care of it for you.
If you have a big Anubias plant and want to spread its glory (how cheesy!) throughout other parts of the tank (or other tanks) cut it at the rhizome. You will see that the root system consists of a whole bunch of roots originating at a thick base root, this is where you cut. As this plant is a slow grower, other fast growing plants should be included to assist in sucking up of algae causing chemicals (faster growers eat more to build tissue).
I have a giant Anubias in the front of my 75 liter community tank. It's still relatively new, so has not begun to produce flowers yet. It's stunning up front. Even more so when my Whiptail Cat attaches itself to a giant leaf and sways with the current. In my CO2 enriched tank the plant has shown vigorous growth under two 40W Vita-light fluorescent bulbs. I use Kent's Plant fertilizer once a week adding 2 and a half capfuls (approx. 12 mL) per 75 liters.
The Anubias need to be safe from the direct light. Otherwise, they will be covered with algae. It's advisable to locate them in places where the light will be weak or under plants and objects of greater size. Also, that weak light must have sufficient quality to obtain a growth and an expansion of the plant.
