Can Forktail Blue-eye and Red Goldflake Shrimp Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Possible with Caution

Keeping Forktail Blue-eye and Red Goldflake Shrimp together is possible but requires caution due to potential behavioral clashes. Provide a spacious tank of at least 55 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Forktail Blue-eye and Red Goldflake 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

Forktail Blue-eye is a peaceful species (2/10), while Red Goldflake Shrimp is peaceful (0/10). This modest difference means Forktail Blue-eye may occasionally assert dominance over Red Goldflake Shrimp.

In terms of spatial distribution, Forktail Blue-eye prefers the Top (Surface) and Middle (Open Water) zones, whereas Red Goldflake Shrimp occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Forktail Blue-eye is a known jumper, so a tight-fitting lid is essential.

To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

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. 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 Forktail Blue-eye and Red Goldflake Shrimp together, plan for an aquarium of at least 55 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.

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: Plants - Densely covered, 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 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. Forktail Blue-eye and Red Goldflake Shrimp 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.

What size tank do Forktail Blue-eye and Red Goldflake Shrimp need?

A minimum of 55 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 Forktail Blue-eye and Red Goldflake 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 Forktail Blue-eye or Red Goldflake Shrimp aggressive?

Forktail Blue-eye is peaceful (2/10) and Red Goldflake Shrimp is peaceful (0/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Forktail Blue-eye and Red Goldflake 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.
