Guppy Tank Mate Compatibility Chart
Guppy Tank Mate Compatibility Chart
Use this chart as a fast starting point for planning a guppy community. It compares temperament, fin safety, water overlap, baby-guppy risk, space needs, and the main issue to watch with each companion. A “good” rating does not replace proper group size, tank size, filtration, or species-specific care—but it quickly shows which combinations are easiest and which deserve caution.

Best overall choices for a low-stress guppy community
If the goal is a peaceful, easy-to-manage aquarium, prioritize tank mates that use different zones, do not nip fins, and share similar water conditions.
Best all-around guppy tank mates
Corydoras
Excellent temperament match, bottom-zone activity, and almost no interest in guppy fins.
Nerite Snails
Extremely low-conflict, visually interesting, and one of the safest choices around baby guppies.
Platies
Very strong water overlap and similar care, with population control being the main management issue.
Amano Shrimp
Peaceful larger shrimp that add grazing behavior without crowding the open water.
Otocinclus
Very gentle fish for mature planted aquariums, especially when fry safety matters.
Choose tank mates based on what you want the aquarium to do
Lowest Aggression
Nerite Snails, Corydoras, Otocinclus, and Amano Shrimp.
Best Hard-Water Match
Platies, Mollies, Swordtails, Endlers, and other guppies.
Best for Baby Guppies
Nerite Snails and Otocinclus rank especially well when newborn safety is the priority.
Best Bottom Activity
Corydoras, Kuhli Loaches, Otocinclus, and Bristlenose Plecos.
Best Schooling Look
Harlequin Rasboras and Cherry Barbs are among the more realistic choices.
Best Centerpiece Option
Honey Gourami is generally easier than more territorial Gouramis or Angelfish.
Baby-guppy safety is a separate compatibility question
Many fish rated “good” with adult guppies will still eat newborns. Always use the fry-risk column if breeding or baby survival matters.
Best and worst companions for newborns
Nerite Snails and Otocinclus.
Amano Shrimp and many peaceful bottom dwellers.
Rasboras, barbs, livebearers, and adult guppies.
Gouramis, Angelfish, Goldfish, and predatory fish.
Fancy tails need a stricter compatibility filter
Large-tailed males are less maneuverable than females and more visually conspicuous. A tank mate that is acceptable with short-finned females may deserve more caution around elaborate male guppies.
Larger bodies help—but pregnancy changes the picture
Females are generally stronger-bodied and less vulnerable to fin damage, but pregnant females may need quieter areas and easier feeding access. Pushy male livebearers and hyperactive schools can create more stress late in pregnancy.
Behavior is only half of the equation
Guppies generally prefer stable, mineral-rich freshwater. Livebearers such as Platies, Mollies, and Swordtails often match that environment very well. Soft-water species can still be possible, but the tank should not be pushed to extremes just to force a mixed community.
When to reconsider a tank mate
Repeated chasing, torn tails, one guppy hiding constantly, unexplained missing fish, missed meals, rapid breathing, or a growing size gap are all reasons to reassess compatibility.
Compatibility can change as fish mature. Juvenile behavior should never be treated as a guarantee of adult behavior.
Before adding any new tank mate, check these six things
Could the new fish eventually swallow a guppy?
Is the species known to nip flowing fins?
Does it actually fit warm, mineral-rich guppy water?
Does it need several of its own kind?
Will one species consistently outcompete the other?
Will newborn guppies become prey?
What makes compatibility charts misleading when used incorrectly?
Ignoring tank size
A “good” pairing can still fail in an overcrowded aquarium.
Ignoring group needs
Schooling fish and social bottom dwellers require enough of their own kind.
Ignoring individual behavior
Some Gouramis and Bettas vary dramatically from fish to fish.
Planning around juveniles
Adult size and mature behavior matter more than pet-store size.
Assuming adult-safe means fry-safe
Newborn guppies change the compatibility calculation completely.
Chasing perfect numbers
Stable water is better than constantly changing pH or hardness to force a compromise.
Guppy Compatibility Chart FAQ
What is the best overall tank mate for guppies?
Corydoras are one of the strongest all-around choices because they are peaceful, social, and use a different part of the tank.
What is the safest tank mate for baby guppies?
Nerite Snails are among the lowest-risk choices because they cannot chase or swallow healthy fry.
What fish should be avoided with guppies?
Tiger Barbs, adult Angelfish, Goldfish, and large aggressive or predatory fish are among the clearest poor matches.
Are livebearers always good with guppies?
They often share excellent water requirements, but adult size, male aggression, and rapid breeding still need management.
Can guppies live with schooling fish?
Yes, when the school is peaceful, properly sized, and compatible with the tank's temperature and water hardness.
Are bottom dwellers good guppy tank mates?
Often yes. Corydoras, Otocinclus, Kuhli Loaches, and Bristlenose Plecos can reduce direct swimming-space competition.
Why can a pairing be “conditional” instead of simply yes or no?
Some combinations depend strongly on individual behavior, temperature compromise, tank size, group size, or whether baby guppies need protection.
Does a compatibility chart replace species research?
No. Use it to shortlist options, then check the full species-specific guide before adding a tank mate.
