Polka Dot Loach

The Polka Dot Loach, also known as the Burmese Border Loach or Angelicus Loach, is a strikingly patterned loach from Myanmar. These fish feature a beautiful mottled pattern of dark brown or black spots and blotches on a yellowish-cream background, creating a polka dot appearance that makes them highly sought after. They have an elongated, streamlined body shape typical of botia loaches and are active, social fish that display fascinating behaviors. Like many loaches, they are known for their clicking sounds produced by grinding their pharyngeal teeth. Polka Dot Loaches are relatively new to the aquarium trade but have quickly become popular due to their stunning appearance and manageable size compared to larger loach species like the Clown Loach. Their peaceful nature and interesting behaviors make them an excellent choice for community tanks with appropriate tank mates.

Care Requirements

Tank Setup

Polka Dot Loaches need a spacious tank with plenty of hiding spots and soft substrate. A 40-gallon tank accommodates a group of 5-6 individuals. Provide rocky caves, driftwood, and plants for cover. They appreciate moderate water flow and excellent filtration. Smooth gravel or sand substrate protects their sensitive undersides during their constant foraging.

Water Quality

• Temperature: 75-82°F (24-28°C)
• pH: 6.5-7.5
• Water Hardness: Soft to moderate, 2-15 dGH
• Ammonia/Nitrite: 0 ppm
• Nitrate: <20 ppm

Feeding

These omnivores accept sinking pellets, algae wafers, and frozen or live foods. They are enthusiastic eaters that appreciate variety in their diet. Offer bloodworms, brine shrimp, and vegetable matter. Feed after lights out or in the evening when they are most active. Ensure food reaches the bottom where they feed.

Behavior & Compatibility

Polka Dot Loaches are social fish that should be kept in groups of 5 or more to exhibit their natural behaviors and reduce stress. They are peaceful and suitable for community tanks with other non-aggressive species. They may occasionally eat small snails in the tank. Their active nature and social behaviors make them entertaining additions to appropriate setups.

Tips for Success

• Keep in groups of 5+ for natural social behaviors and clicking communication
• Provide multiple caves and hiding spots to establish territories
• Use soft substrate to protect their bellies during bottom foraging
• They are nocturnal but will become active during the day once settled
• Maintain excellent water quality with regular changes
• Their beautiful pattern becomes more defined with age and proper care
