Can Amano Shrimp and Clown Pleco (L104) Live Together?

Amano Shrimp is a peaceful species (1/10), while Clown Pleco (L104) is generally mild-mannered (3/10). This modest difference means Clown Pleco (L104) may occasionally assert dominance over Amano Shrimp.

Amano Shrimp and Clown Pleco (L104) 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

Worth noting: Clown Pleco (L104) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Amano Shrimp 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 Amano Shrimp and Clown Pleco (L104) 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.

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

Both fish can tolerate a pH between 6 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 4–14 dGH. Regular testing will ensure conditions stay within this range.

To house Amano Shrimp and Clown Pleco (L104) together, plan for an aquarium of at least 90 litres with a minimum length of 60 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: Established Algae (Otocinclus), Plants - Densely covered, 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.

Feeding time deserves special attention with this pairing. Amano Shrimp is an aggressive eater that may prevent Clown Pleco (L104) from getting enough food.

Because Amano Shrimp is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Clown Pleco (L104) receives an adequate share.
