The wild coloring of this fish is quite variable. Most often they will have yellowish sides and are browner on top. There is a notable black stripe running along the sides from the tip of its "nose" to its tail. This stripe is often broken and there can be black spotting along its back and on the tail fin. There are a number of color morphs available as well, like the popular gold variety called the Golden Chinese Algae Eater. Other varieties include albino, marble, and lecustic forms.

A number of fish from the minnow/carp family make good algae eaters. The flying fox (Epalzeorhynchos kalopterus) will nibble on algae. Additionally, the Siamese algae eater (Crossocheilus siamensis) will eat brush algae—which many algae eaters ignore. However, the Siamese algae eater closely resembles other species, some of which make poor algae eaters and may pick on tetras. To determine if you have a real Siamese algae eater, look at the stripe on the side of the tail. On true Siamese algae eaters, you will see a solid black stripe that runs from the tip of the nose through the eye and straight through the center of the tail. If the stripe stops at the base of the tail or you see more than one line, you have something else. Sucker Black Fish ( Algae Eater) in Action of Cleaning Aquarium Glass.

The strands don't usually get very long, one centimeter is the usual size.

The algae usually forms on slow-growing plants such as Anubias, but it can also grow on gravel, diftwood, or rocks in your tank.

How To Remove:

Using different fish or snails: There are a few different types of fish known to eat BBA,
Siamensis, CAE / SAE Algae Eaters, Black Mollies, Angelfish may eat it. Apple snails will also eat BBA.

Algae Eating Shrimp: Japonica Shrimp (Caridina japonica).

Chemical fixes:

Before doing this, it is recommended that you take out all the decorations covered with the BBA and soak then in a mild bleach and water solution. That will kill the Algae, and then you should scrub the plants with a soft brush to get it off to help it from growing back.

(If using live plants you can do the same, however I find it easer to just remove the leaf.)

Warning: Using too much bleach can remove the dies.

You can Soak wood as well but you will have make sure you really rinse it out well. You do not want left over bleach getting into your tank.

Flourish Excel: Works great if your tank is planted, and that is cause for your Black Hair. And diluted amounts are said to work well in non-planted tanks thats have contracted it.

Lighting: Reducing your light to 6 hours a day will cut back on the growth, which will help when using a chemical fix.

Algaefix, works well to.


The biggest reason you get BBA iis that your plants aren't getting the right amount of support they need. Lowlight, not even nutrients in the water.Do not be confused with Flying Fox which looks similar but with different characteristicswhich makes them less desirable for your community tanks. SAEs are peaceful and are goodalgae eaters. They grow up to 6 inches so you will need a decent sized tank - at least 30x12inch footprint. Once they hit around 4 inches, they will not eat algae as well. Most storeswill sell them at 2 inches in size, so if you are looking for a long term solution, this maynot work for you. They will eat variety of algaes but I have never seen them eat long strandsof hair algae. If they are hungry, they will eat black beard algae. They are often suggestedas a schooling fish, and if you have more than one, they often swim together. But unlike mostschooling fishes, SAE can be kept in singles.The strands don't usually get very long, one centimeter is the usual size.
