Electric Blue Acara tank mates
Electric blue acara tank mates fail when shops promise a long “usually safer” list. The live engine currently marks no GOOD companions for this semi-aggressive cichlid — every listed neighbour is caution. Corydoras, bristlenose, harlequin rasboras, and pearl gouramis can work as situational tank mates in a large planted layout with caves and a clear exit plan, but they are not green-light community stickers. Neon-class dither fish disappear once the mouth catches up. Plan roughly 150–200L with broken sight lines, then open every caution name as a pair check — not a shopping list copied from a peaceful tetra hub.
Common mistakeStocking electric blue acaras with nano tetras under about 4 cm is how keepers invent disappearances as the acara matures. Adult gape treats small fish as prey even if juveniles coexisted for months. Choose robust companions from day one — or keep a species-focused setup.
