Red zebra cichlids are territorial Lake Malawi mbuna. Their color makes them popular, but successful care depends on an adult stocking plan, stable mineral-rich water and enough separate refuges. They are not general community fish.
Identity, adult size and color
The species is widely listed as Maylandia estherae and Metriaclima estherae. Adults commonly approach 4–5 inches, with males generally larger. Orange, blue and blotched forms occur; an orange fish is not automatically female. Obtain the locality or strain information from the breeder.
Rick Borstein’s firsthand breeding account for the Greater Chicago Cichlid Association describes several color forms and adult size differences. Egg spots and fin shape can help with sexing, but counting a fixed number of spots does not reliably identify every individual.
Tank size and rockwork
Plan a four-foot aquarium for an adult group; a 75-gallon tank with an approximately 48 × 18 inch base gives more useful territory than a shorter tank of similar volume. Mixed mbuna communities and competing males may need substantially more space. Have an established separation tank available.
Use sand and stable rockwork with multiple caves, broken sight lines and escape routes. Place and secure heavy rocks before fish can undermine them. A subordinate fish needs somewhere to feed and rest, not just one hiding hole beside the dominant male’s territory.
One male with at least three females is a common species-group arrangement. It reduces attention on any single female but does not guarantee peace. Do not add fish indiscriminately to “overcrowd away” aggression: stocking more heavily increases waste, oxygen demand and the consequences of filtration failure.
Water conditions and maintenance
The red zebra species profile gives 24–28°C, pH 7.6–8.8 and 10–25°dGH as care ranges. Aim for stable conditions within a suitable part of the range; the extremes are not targets to alternate between.
Test tap water for pH, GH and KH before choosing a buffer or mineral supplement. Tap-water chemistry varies widely. Marine salt is not a substitute for freshwater mineral balance, and breeding does not automatically require a bottled “cichlid salt.”
Establish the biological filter before adding fish. Keep ammonia and nitrite at zero, monitor nitrate, maintain good surface movement and make regular partial water changes. Match replacement-water conditions and remove accumulated waste during routine maintenance.
Feeding
Use a complete mbuna food with substantial algae or vegetable ingredients, offered in modest portions. Red zebras also consume animal material; algae growing on rocks alone will not support a stocked aquarium. Avoid rich meat-based feeding and remove uneaten vegetables before they foul the water.
Swelling and loss of appetite are signs to investigate, not proof that one meal caused “Malawi bloat.” Check water quality and aggression promptly and seek a diagnosis if the fish deteriorates. Do not medicate the entire aquarium on the basis of swelling alone.
Tank mates and breeding
Assess other mbuna by species, adult temperament, diet and space. Being from Lake Malawi does not make every cichlid compatible: quieter peacock cichlids can be overwhelmed. Tiny community fish, shrimp and slow long-finned fish are poor choices.
Females mouthbrood, usually releasing developed fry after roughly three to four weeks. Avoid disturbing a holding female unnecessarily. If isolation is needed, use a cycled setup and plan for her later return. Free-swimming fry with absorbed yolk sacs can eat appropriately fine prepared food and newly hatched brine shrimp.
Keep different color forms and closely related species separate when preserving identified breeding lines. Do not distribute offspring as pure red zebras if hybridization is possible.
