You can house multiple Chinese algae eater fish in a single habitat but it is best to keep at least six species. It prefers a mature well-filtered planted aquarium with lots of hiding places. The tank should have shaded areas because they tend to like to avoid the bright aquarium lights at times. It does well in stronger currents with well oxygenated water. As this fish matures it becomes aggressive towards tank mates and con-specifics. They should not be kept with smaller fish such as Neon Tetras or slow moving high-backed fish such as Angelfish and Discus. They must never be kept with Goldfish. They also do well in semi-aggressive fish such as African Mbuna Cichlids. The Chinese algae eater can sometimes jump out of tanks so you need a good hood to prevent jumping. It prefers good water chemistry with pH of 6.5 -7.5, water hardness 8 to 12° dKH and temperature 75 – 80° F. 25 – 50% of the tank water should be changed at least once a month. If the tank is densely stocked 20-25% should be replaced weekly or every other week.
