Gymnogeophagus balzanii or Paraguay Eartheater.

The fish that you will receive will measure around 7-10cm. It will take a little time to show its full coloration. 
We also reccommend that you keep the tank dark as they do prefer black water. Make sure that you have plenty of oxygen in the tank as they love the bubbles. 

Large Community as males do grow to around 20cm                                                                                                              

These fish are very peaceful cichlids. They are a bit of a scavenger and will continually sift through the sand and stones on the bottom for anything that they can eat. As the name suggests, be aware they will more substrate and rocks around in the tank.

Adult Length: 20cm

Temperature Range 21-25°C at standard but do need a cooler period.

pH Range: 6.5-7.8

Special Requirements:  Fairly easy to keep.

Tanks Mates:  Any South American larger community fish under 15cm, providing they are not too large to intimidate the Eartheater. THey can be housed happily with some of the large tetras etc.

Feeding: .  Like to sift feed, meaning they will take large mouthfuls of debris and pick out the tastey bits of food. Ideally fed on pellets but will eat virtually anything that it can find.
