Can your tank handle Keyhole Cichlid and Raspy River Stingray?

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

Keyhole Cichlid is a peaceful species (2/10), while Raspy River Stingray is generally mild-mannered (4/10). This modest difference means Raspy River Stingray may occasionally assert dominance over Keyhole Cichlid.

Keyhole Cichlid and Raspy River Stingray both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

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 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 2–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Keyhole Cichlid and Raspy River Stingray together, plan for an aquarium of at least 850 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.

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: Driftwood (Digestion/Hiding), Plants - Densely covered, Leaf Litter/Blackwater, Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Raspy River Stingray is a plant destroyer, which conflicts with Keyhole Cichlid's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Why This Pairing Needs Extra Planning in Practice

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Keyhole Cichlid and Raspy River Stingray need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

Frequently Asked Questions

Can Keyhole Cichlid and Raspy River Stingray live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 850 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Keyhole Cichlid and Raspy River Stingray need?

A minimum of 850 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 Keyhole Cichlid and Raspy River Stingray 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 Keyhole Cichlid or Raspy River Stingray aggressive?

Keyhole Cichlid is peaceful (2/10) and Raspy River Stingray is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Keyhole Cichlid and Raspy River Stingray 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.
