Can Achara Catfish and Butterfly Pleco (L168) Live Together?

Possible with Caution

Keeping Achara Catfish and Butterfly Pleco (L168) together is possible but requires caution due to differing aggression levels. Provide a spacious tank of at least 1500 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Behaviour & Temperament

Achara Catfish is a moderately assertive species (6/10), while Butterfly Pleco (L168) is peaceful (2/10). This notable difference means Achara Catfish may occasionally assert dominance over Butterfly Pleco (L168).

Achara Catfish and Butterfly Pleco (L168) 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: Achara Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

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 Achara Catfish and Butterfly Pleco (L168) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. 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 25Β°C and 28Β°C. Aim for the midpoint of this range (around 26.5Β°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 4–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Achara Catfish and Butterfly Pleco (L168) together, plan for an aquarium of at least 1500 litres with a minimum length of 240 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 β€” caves, driftwood, and dense plant clusters β€” so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). 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.

Frequently Asked Questions

Can Achara Catfish and Butterfly Pleco (L168) live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 1500 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Achara Catfish and Butterfly Pleco (L168) need?

A minimum of 1500 litres (tank length at least 240 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 Achara Catfish and Butterfly Pleco (L168) together?

Keep the aquarium between 25Β°C and 28Β°C. A target of around 26.5Β°C sits comfortably within both species' preferred ranges.

Are Achara Catfish or Butterfly Pleco (L168) aggressive?

Achara Catfish is moderately assertive (6/10) and Butterfly Pleco (L168) is peaceful (2/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Achara Catfish and Butterfly Pleco (L168) need?

Both species overlap in the 6–7 pH range. Consistency is key β€” avoid sudden swings, and test regularly to stay within this window.

How do I manage Butterfly Pleco (L168)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Butterfly Pleco (L168) space to claim a territory without encroaching on the other fish's area. Adding dΓ©cor that divides the tank into distinct zones works especially well.

Does Achara Catfish being nocturnal affect compatibility?

Achara Catfish 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 Achara Catfish during evening hours.
