Can Blind Cave Tetra and Orange Delight Shrimp Live Together?
Blind Cave Tetra and Orange Delight Shrimp are not recommended as tank mates due to no temperature overlap. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle Blind Cave Tetra and Orange Delight Shrimp?
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
Blind Cave Tetra is a generally mild-mannered species (4/10), while Orange Delight Shrimp is peaceful (0/10). This notable difference means Blind Cave Tetra may occasionally assert dominance over Orange Delight Shrimp.
Blind Cave Tetra and Orange Delight Shrimp 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
There is no temperature overlap between Blind Cave Tetra (20–25°C) and Orange Delight Shrimp (26–29°C). This fundamental mismatch makes long-term cohabitation impractical.
Both fish can tolerate a pH between 7.5 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 8–8 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Blind Cave Tetra and Orange Delight Shrimp together, plan for an aquarium of at least 110 litres with a minimum length of 80 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: Smooth Gravel (Sensitive Barbels), Sand (Sifters), Established Algae (Otocinclus). 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
Blind Cave Tetra and Orange Delight Shrimp 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.

Frequently Asked Questions
Can Blind Cave Tetra and Orange Delight Shrimp live together?
No. This combination is not recommended. Key incompatibilities — such as non-overlapping temperature ranges — make cohabitation unsafe.
What size tank do Blind Cave Tetra and Orange Delight Shrimp need?
A minimum of 110 litres (tank length at least 80 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 Blind Cave Tetra and Orange Delight Shrimp together?
Unfortunately, there is no temperature range that satisfies both species. Blind Cave Tetra requires 20–25°C, while Orange Delight Shrimp needs 26–29°C.
Are Blind Cave Tetra or Orange Delight Shrimp aggressive?
Blind Cave Tetra is generally mild-mannered (4/10) and Orange Delight Shrimp is peaceful (0/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Blind Cave Tetra and Orange Delight Shrimp need?
Both species overlap in the 7.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Blind Cave Tetra nip Orange Delight Shrimp's fins?
Blind Cave Tetra is a known fin nipper. If Orange Delight Shrimp has long or flowing fins, there is a real risk of fin damage. Keeping Blind Cave Tetra in a larger group can help redirect nipping behaviour toward conspecifics.
