Acara Rivulata or Green Terror

As the name Green Terror might suggest, this is not a peaceful member for a community tank. The A. Rivulata is a medium sized rather aggressive Cichlid, from South America. Males can grow to about 8” and females to about 6” in length.

This member of the Acara Cichlid family is only suited for larger tanks (60+ gallons). As decoration and as cover for the fish you should decorate your tank with rocks and wood.

The Green Terror is a powerful fish and will start digging and eating away the roots of your plants almost in a minute. So, if you want to use plants, pot very strong species of the plants before you put them under the gravel. Make sure to use gravel with rounded edges as a bottom layer so that the fish doesn’t hurt itself as it digs.

It’s best to keep these Cichlids in pairs. Once fully grown, they can be very harmful to other inhabitants of the tank. For that reason, they are usually kept in a specialty tank, either alone or with some other strong Cichlids. It is very important that the tank is spacious and has enough hiding places for these fish. These guys are territory forming and are very aggressive to intruders.

Water Conditions

Keep the Green Terror (A. Rivulata) at a water temperature between 68-77F. The best pH is somewhere in the 6.5–6.8 range and the water hardness from 5–8 dH. Good water conditions are important for the A. Rivulata, especially if you want to enjoy their full range of colors or breed them.

The females are smaller than the males and are more darkly colored. The male develops a large hump on the forehead as his age progresses. This is normal and certainly not a sign of illness.

Feeding

The Green Terror is known for its appetite. As basic food, you can use special cichlid flakes or sticks, but these fish do require live food as well.

When you increase the normal water temperature a few degrees and other circumstances are good, a pair will normally start breeding. Eggs are deposited on rocks or wood and are heavily defended. The parents care for their hatchlings for a fairly long time.
