Angelfish tank mates
Angelfish tank mates fail in two directions, and this hub will not pretend there is a long “usually safer” list. The live engine currently marks no GOOD companions for angelfish — every listed neighbour is caution or avoid because adult angels are territorial cichlids with a mouth that fits neon-sized fish. Tiger barbs sit in avoid for fin shredding. Neons and similar small dither fish sit in avoid for predation — growing up together does not change the adult mouth-size outcome. Corydoras, harlequin rasboras, and calm gouramis are caution — workable only with height, cover, and a pair check. Plan a tall 150L floor — honestly a planted 200L — then open every caution name as a pair check, not a shopping list.
Common mistakeBuying six juvenile angels for a 60L community is the classic territory bomb. When a pair forms they claim glass and wipe out tank mates that shared the tank for months. Start with tall 150L-class height, plan for a bonded pair, and never trust a shop chart that lists neon tetras as permanent roommates.
Each name below opens a pair check with Angelfish. That check is the decision, not the list itself.

Risky or situational
May work with more water, a mature system, or a species-only setup. Read the pair page before you experiment.
Marked risky or situational on the profile. Tank length and group size change the outcome more than a temperament label does.
Jack Dempsey is flagged predatory. Equal-size adults usually coexist, but the moment one is stressed, sick, or smaller after a moult, it becomes prey. Both species defend territory. The pairing needs a long footprint and rockwork or planting that breaks the sightline between two defended spots. Jack Dempsey is rated aggressive, so expect chasing, fin damage, or display behaviour directed at Angelfish. Run the pair checker before stocking.
Oscar reaches 35cm and is flagged predatory or as likely to eat small fish. Adult-size Angelfish at 20cm is inside that gape range. Both species defend territory. The pairing needs a long footprint and rockwork or planting that breaks the sightline between two defended spots. Oscar is rated aggressive, so expect chasing, fin damage, or display behaviour directed at Angelfish. Run the pair checker before stocking.
