CompatibilityThe false blue neon is a peaceful schooling species suitable only for calm community aquariums with small, non-aggressive fish in similar (soft, slightly acidic) water conditions. It should be kept in groups of at least 8–10 (preferably more) individuals. Good tank mates include other small neons, small tetras, rasboras, Corydoras, small sucker catfish. It is strictly not recommended to keep larger, predatory, or aggressive fish such as angelfish, gouramis, large catfish, cichlids, and goldfish — such small fish are easily perceived as food by them. Due to its small size and water requirements, this species is not considered a universal inhabitant of general community tanks.
Plant safetySafe
Plant-eating behaviourThe species does not eat or damage plants. In nature, it is an omnivorous micro-predator: feeds on small invertebrates, crustaceans, filamentous algae, and fallen fruits; live aquarium plants are not part of its diet. Conversely, the species is recommended to be kept in densely planted aquariums, where thickets and shade-tolerant plants (anubias, crypts, ferns, Java moss) serve as cover and part of the natural decor.
Interaction with invertebratesThe species is peaceful towards invertebrates: safe for adult dwarf shrimp (e.g., cherry shrimp) and small peaceful invertebrates, as its small mouth prevents it from swallowing adult shrimp. However, like other neons, it may hunt juveniles and very small shrimp, so shrimp fry are better kept separately or provided with hiding places.
Incompatible groupsLarge and predatory fish that may perceive neon as prey (large cichlids, large catfish, angelfish, gouramis), as well as large and active species creating competition for food, are unsuitable. Species requiring alkaline, hard water are undesirable — they are incompatible with the soft, acidic conditions necessary for neon.
