Behavior

What kind of behavior does the Chinese algae eater have?

It is a territorial and aggressive fish. Initially, little Sucking Loach spends its time hiding, but its territorial temperament is affirmed when it grows. In a group of 5 or 6, intraspecific aggression will decrease significantly and fish will develop a distinct hierarchy. This requires a nice volume (250 L / 55 imp gal / 66 US gal). In a group that is too small, the weakest individuals will be systematically targeted. It is also very keen.

Cohabitation

Who can live with the Chinese algae eater?

Cohabitation

Who can live with the Chinese algae eater?

A specific aquarium is preferable (with its congeners in large volumes).

If you want to keep it in a community aquarium, you will have to choose your roommates carefully. Indeed, the Sucking Loach becomes very aggressive in aging and especially towards the fish which resembles him, like Crossocheilus, Epalzeorhynchos or Garra.

It will be necessary to avoid associating it with calm and timid fish, as well as large placid fish on which it will sometimes try to stick. In the same way, avoid cohabitation with groundfish such as Corydoras or small Cichlids. Finally, it should be noted that it is likely to eat small fish.

You can combine it with strong, lively species such as sumatra beards or Etroplus.

Which aquarium for the Chinese algae eater?

The Chinese algae eater likes clear waters and moderate currents: choose a good filtration. It will allow good oxygenation of the water and will also prevent the accumulation of organic waste.

In general, the aquarium of this fish must be very planted because it likes to hide.

Planning idea: to reproduce a flowing river. For this, add to your decoration gravel, rocks worn by water (rather round, like pebbles) of different sizes and some big rocks. You can complete with some branches and driftwood roots. Finally, attach plants such as Bolbitis, Anubias or Microsorum to your decoration.

Note that powerful lighting will encourage the growth of algae, which the Sucking Loach will feast!
