Black Belt Cichlid (Vieja maculicauda) is an intermediate-level freshwater fish that needs at least 125 gallons and 72-82°F. A big, strong Central American cichlid sold small but growing to a foot or more. It is a digger with a bad temper toward other cichlids, so it needs a large tank, heavy equipment and tankmates that can handle it.

Quick tips

  • Plan for a tank of 125 gallons or more for an adult.
  • Secure rocks and equipment; it digs and moves decor.
  • Do not mix with small or timid fish.

San Diego water

Naturally suited to San Diego's hard, alkaline tap water once it is dechlorinated (the city uses chloramine, so use a conditioner that handles it). Learn the numbers in our San Diego tap water guide.

Before you buy

Make sure your tank is cycled (how to cycle a tank), check your numbers with the water testing guide, and use the compatibility guide to check tankmates. These are general ranges; individual fish and local water vary.
