This is a very nice and colorful fish to have. Trewavasae's make great community fish and it is easy to tell the males from the females. Females are this OB color (OB = Orange Blotch) pattern and the males are a bright blue with a red Top or Dorsal fin, hence the name Red Top. This fish is a mouth brooder and I have had many batches of fry. This fish will produce around 20 fry per batch and you can tell males from females at birth. The juvenile males are a dark color with stripes when born. When they get to about 2" or so they will start to change color. With most Cichlids, breeding brings out the best color, so it's always a good idea to have both males and females. My Trewavasae's started breeding at about 2.5" to 3" long. I kept 2 males and 4 females, this also helps keep the males very nicely colored when they have a rival in the tank.
Tank Size: 75 gallon (this is where I had mine but they did very well in a 20 gallon tank)
