Can Figure 8 Puffer (Brackish) and Orange Delight Shrimp Live Together?
Figure 8 Puffer (Brackish) and Orange Delight Shrimp are not recommended as tank mates due to incompatible water types and incompatible hardness ranges. 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 Figure 8 Puffer (Brackish) 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
Figure 8 Puffer (Brackish) is a semi-aggressive species (8/10), while Orange Delight Shrimp is peaceful (0/10). This notable difference means Figure 8 Puffer (Brackish) may occasionally assert dominance over Orange Delight Shrimp.
Large aggression gap (8 points) between Figure 8 Puffer (Brackish) and Orange Delight Shrimp increases stress risk for the more peaceful fish.
Figure 8 Puffer (Brackish) 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.
Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.
Water Parameters
The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.
Both fish can tolerate a pH between 7.5 and 8.5. Maintaining a stable value within this band is more important than hitting an exact number.
Hardness requirements are incompatible: Figure 8 Puffer (Brackish) needs 10–25 dGH while Orange Delight Shrimp requires 4–8 dGH.
Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.
Tank Setup
To house Figure 8 Puffer (Brackish) and Orange Delight Shrimp together, plan for an aquarium of at least 60 litres with a minimum length of 60 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), Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels), 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
Figure 8 Puffer (Brackish) 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 Figure 8 Puffer (Brackish) and Orange Delight Shrimp live together?
No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.
What size tank do Figure 8 Puffer (Brackish) and Orange Delight Shrimp need?
A minimum of 60 litres (tank length at least 60 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 Figure 8 Puffer (Brackish) and Orange Delight Shrimp together?
Keep the aquarium between 26°C and 28°C. A target of around 27.0°C sits comfortably within both species' preferred ranges.
Are Figure 8 Puffer (Brackish) or Orange Delight Shrimp aggressive?
Figure 8 Puffer (Brackish) is semi-aggressive (8/10) 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 Figure 8 Puffer (Brackish) and Orange Delight Shrimp need?
Both species overlap in the 7.5–8.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Figure 8 Puffer (Brackish) nip Orange Delight Shrimp's fins?
Figure 8 Puffer (Brackish) is a known fin nipper. If Orange Delight Shrimp has long or flowing fins, there is a real risk of fin damage. Keeping Figure 8 Puffer (Brackish) in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Figure 8 Puffer (Brackish)'s territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Figure 8 Puffer (Brackish) 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.
