Can Reticulated Stingray (Teacup Ray) and White Cloud Mountain Minnow Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Reticulated Stingray (Teacup Ray) and White Cloud Mountain Minnow are not recommended as tank mates due to no temperature overlap and piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Reticulated Stingray (Teacup Ray) and White Cloud Mountain Minnow?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

Reticulated Stingray (Teacup Ray) is a generally mild-mannered species (4/10), while White Cloud Mountain Minnow is peaceful (1/10). This modest difference means Reticulated Stingray (Teacup Ray) may occasionally assert dominance over White Cloud Mountain Minnow.

In terms of spatial distribution, Reticulated Stingray (Teacup Ray) prefers the Bottom (Substrate) zone, whereas White Cloud Mountain Minnow occupies the Top (Surface) and Middle (Open Water) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

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..

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

Worth noting: White Cloud Mountain Minnow is a known jumper, so a tight-fitting lid is essential.

Water Parameters

There is no temperature overlap between Reticulated Stingray (Teacup Ray) (24–30°C) and White Cloud Mountain Minnow (14–22°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Reticulated Stingray (Teacup Ray) and White Cloud Mountain Minnow together, plan for an aquarium of at least 680 litres with a minimum length of 180 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: Sand (Sifters), 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.

Why This Pairing Usually Fails in Practice

Reticulated Stingray (Teacup Ray) and White Cloud Mountain Minnow are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Reticulated Stingray (Teacup Ray) and White Cloud Mountain Minnow.

Diet & Feeding

Feeding time deserves special attention with this pairing. Reticulated Stingray (Teacup Ray) is a known shrimp eater and may prey on small invertebrates or nano fish like White Cloud Mountain Minnow.

Frequently Asked Questions

Can Reticulated Stingray (Teacup Ray) and White Cloud Mountain Minnow live together?

No. This combination is not recommended. Key incompatibilities — such as non-overlapping temperature ranges — make cohabitation unsafe.

What size tank do Reticulated Stingray (Teacup Ray) and White Cloud Mountain Minnow need?

A minimum of 680 litres (tank length at least 180 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 Reticulated Stingray (Teacup Ray) and White Cloud Mountain Minnow together?

Unfortunately, there is no temperature range that satisfies both species. Reticulated Stingray (Teacup Ray) requires 24–30°C, while White Cloud Mountain Minnow needs 14–22°C.

Are Reticulated Stingray (Teacup Ray) or White Cloud Mountain Minnow aggressive?

Reticulated Stingray (Teacup Ray) is generally mild-mannered (4/10) and White Cloud Mountain Minnow is peaceful (1/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Reticulated Stingray (Teacup Ray) and White Cloud Mountain Minnow need?

Both species overlap in the 6–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
