Appearance and identification
"Pearl" here means iridescence, not the pale spots of celestial pearl danios. Trade fish may be similar species or hybrids.
Same-species behaviour
Keep at least 8–10.
Space requirements
Use a 90 × 30 cm base.
Diet and feeding
Provide suitable prepared foods and small live or frozen foods; watch for feeding competition.
Compatibility limits
Check predation, feeding competition, space and water needs before choosing tankmates.
Aquarium environment
Combine planted margins with open swimming space. Iridescence changes with light and condition.
