Can Freshwater Angelfish and Guppy Live Together?
Keeping Freshwater Angelfish and Guppy together is possible but requires caution due to differing aggression levels. Provide a spacious tank of at least 180 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Freshwater Angelfish is a moderately assertive species (6/10), while Guppy is peaceful (1/10). This notable difference means Freshwater Angelfish may occasionally assert dominance over Guppy.
Freshwater Angelfish and Guppy both frequent the Middle (Open Water) and Top (Surface) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.
To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Freshwater Angelfish and Guppy to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.
Water Parameters
The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.
Both fish can tolerate a pH between 7 and 7.8. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 8–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Freshwater Angelfish and Guppy together, plan for an aquarium of at least 180 litres with a minimum length of 90 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
Specific environmental needs for this combination include: Plants - Densely covered, Driftwood (Digestion/Hiding), Plants - lighly covered, Plants - Floating. Meeting these requirements will help both species thrive.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions
Can Freshwater Angelfish and Guppy live together?▾
They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 180 litres), plenty of hiding spots, and watch for signs of stress or aggression.
What size tank do Freshwater Angelfish and Guppy need?▾
A minimum of 180 litres (tank length at least 90 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.
What water temperature is best for Freshwater Angelfish and Guppy together?▾
Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.
Are Freshwater Angelfish or Guppy aggressive?▾
Freshwater Angelfish is moderately assertive (6/10) and Guppy is peaceful (1/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Freshwater Angelfish and Guppy need?▾
Both species overlap in the 7–7.8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Freshwater Angelfish nip Guppy's fins?▾
Freshwater Angelfish is a known fin nipper. If Guppy has long or flowing fins, there is a real risk of fin damage. Keeping Freshwater Angelfish in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Freshwater Angelfish's territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Freshwater Angelfish space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
