Can Mexican Dwarf Crayfish (CPO) and Tire Track Eel Live Together?
Keeping Mexican Dwarf Crayfish (CPO) and Tire Track Eel together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 816 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Mexican Dwarf Crayfish (CPO) is a generally mild-mannered species (4/10), while Tire Track Eel is moderately assertive (6/10). This modest difference means Tire Track Eel may occasionally assert dominance over Mexican Dwarf Crayfish (CPO).
Mexican Dwarf Crayfish (CPO) and Tire Track Eel 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.
Worth noting: Tire Track Eel is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Tire Track Eel is a known jumper, so a tight-fitting lid is essential.
To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Mexican Dwarf Crayfish (CPO) and Tire Track Eel to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.
Water Parameters
The safe temperature window for both species falls between 22°C and 25°C. Aim for the midpoint of this range (around 23.5°C) for optimal comfort.
Both fish can tolerate a pH between 6.5 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 6–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Mexican Dwarf Crayfish (CPO) and Tire Track Eel together, plan for an aquarium of at least 816 litres with a minimum length of 180 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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: Sand (Sifters), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions
Can Mexican Dwarf Crayfish (CPO) and Tire Track Eel live together?▾
They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 816 litres), plenty of hiding spots, and watch for signs of stress or aggression.
What size tank do Mexican Dwarf Crayfish (CPO) and Tire Track Eel need?▾
A minimum of 816 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 Mexican Dwarf Crayfish (CPO) and Tire Track Eel together?▾
Keep the aquarium between 22°C and 25°C. A target of around 23.5°C sits comfortably within both species' preferred ranges.
Are Mexican Dwarf Crayfish (CPO) or Tire Track Eel aggressive?▾
Mexican Dwarf Crayfish (CPO) is generally mild-mannered (4/10) and Tire Track Eel is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Mexican Dwarf Crayfish (CPO) and Tire Track Eel need?▾
Both species overlap in the 6.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Mexican Dwarf Crayfish (CPO) nip Tire Track Eel's fins?▾
Mexican Dwarf Crayfish (CPO) is a known fin nipper. If Tire Track Eel has long or flowing fins, there is a real risk of fin damage. Keeping Mexican Dwarf Crayfish (CPO) in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Mexican Dwarf Crayfish (CPO)'s territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Mexican Dwarf Crayfish (CPO) 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.
Does Tire Track Eel being nocturnal affect compatibility?▾
Tire Track Eel is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Tire Track Eel during evening hours.
