The red blotch zebra cichlid fish, also known as Maylandia estherae or Metriaclima estherae, is a popular species of cichlid that is native to Lake Malawi in East Africa. As their name suggests, these fish have a stunning appearance with vibrant colors and distinct red blotches on their bodies. Red blotch zebra cichlids are relatively small, growing up to about 4-5 inches long. They are known for their social and active behavior, making them popular for aquarium enthusiasts. However, it's important to note that they can be territorial and aggressive, especially during breeding and when establishing their territories. To keep red blotch zebra cichlids happy and healthy in an aquarium, they should have a spacious tank with plenty of hiding spots and caves to mimic their natural habitat. They prefer a sandy substrate and thrive in water conditions that closely resemble Lake Malawi, including a pH level of around 7.8-8.6 and a temperature range of 76-82°F. In terms of diet, red blotch zebra cichlids are omnivorous and can be fed a variety of high-quality pellets, flakes, and frozen/live foods. It's essential to provide a balanced diet that includes plant matter and protein-rich foods to meet their nutritional needs. Overall, red blotch zebra cichlids are beautiful and fascinating fish to keep, but it's essential to understand their specific care requirements and be prepared for their territorial nature.
