Care notes
Stunning electric blue. Cheap and hardy but very territorial; often used to cycle tanks then proves impossible to remove. Aggression escalates with maturity.
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.
