Care notes
Vivid red body with distinctive black spot behind the gill. Known fin-nippers, especially with slower, long-finned tankmates. Keep in schools of 8+ to reduce nipping behavior. Much better behaved in large schools.
Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
