Angelfish

Planning your aquarium

The library starting point is 29+ US gallons. Plan for the approximate 6-inch adult size and the species' normal activity, not just its current shop size.

The minimum group count is not a compatibility recommendation; assess temperament, sex, territory, and tankmates.

Mixed-species aquariums may need substantially more space. Tank length, adult behavior, filtration, and hiding spaces all matter.

Tank setup and behavior

• Maintain stable, species-appropriate water and provide a mix of cover and swimming room.

Provide a tall tank with vertical structure and room for mature adult fins and territories.

Tall-bodied cichlid that can eat very small fish.

Food and feeding

Food options: Cichlid pellets, Quality flakes, Frozen brine shrimp.

Use appropriately sized, complete staple foods and rotate suitable foods for variety. Feed modest portions and remove uneaten food.

Additional care caution

Adult angelfish may prey on very small schooling fish and baby shrimp.

Tankmate cautions in the checker

• Use caution with Cherry Shrimp: Adult angelfish may eat dwarf shrimp, especially juveniles.
• Use caution with Betta Fish: Both may be territorial and have vulnerable long fins.
• Avoid or investigate Tiger Barb: Tiger barbs can repeatedly nip angelfish fins.
• Use caution with Serpae Tetra: Serpae tetras can nip angelfish fins.
• Avoid or investigate Chili Rasbora: Adult angelfish can treat tiny chili rasboras as prey.
• Use caution with Ember Tetra: Adult angelfish may prey on very small tetras.

These are selected rule-based cautions, not a complete compatibility assessment.
