Behaviour & Temperament
Bluegill Sunfish is a semi-aggressive species (7/10), while White Cloud Mountain Minnow is peaceful (1/10). This notable difference means Bluegill Sunfish may occasionally assert dominance over White Cloud Mountain Minnow.
Large aggression gap (6 points) between Bluegill Sunfish and White Cloud Mountain Minnow increases stress risk for the more peaceful fish.
Bluegill Sunfish and White Cloud Mountain Minnow both frequent the Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.
There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..
Worth noting: White Cloud Mountain Minnow is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 14°C and 22°C. Aim for the midpoint of this range (around 18.0°C) for optimal comfort.
Both fish can tolerate a pH between 6.5 and 8. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 5–20 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Bluegill Sunfish and White Cloud Mountain Minnow together, plan for an aquarium of at least 280 litres with a minimum length of 120 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.
Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.
Specific environmental needs for this combination include: Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), Plants - Densely covered. Meeting these requirements will help both species thrive.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Can Bluegill Sunfish and White Cloud Mountain Minnow live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Bluegill Sunfish and White Cloud Mountain Minnow need?
A minimum of 280 litres (tank length at least 120 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 Bluegill Sunfish and White Cloud Mountain Minnow together?
Keep the aquarium between 14°C and 22°C. A target of around 18.0°C sits comfortably within both species' preferred ranges.
Are Bluegill Sunfish or White Cloud Mountain Minnow aggressive?
Bluegill Sunfish is semi-aggressive (7/10) and White Cloud Mountain Minnow is peaceful (1/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Bluegill Sunfish and White Cloud Mountain Minnow need?
Both species overlap in the 6.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Bluegill Sunfish's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Bluegill Sunfish 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.
