Can Angelicus Pleco L073 and Goldfish (Comet / Common) Live Together?

Angelicus Pleco L073 is a generally mild-mannered species (3/10), while Goldfish (Comet / Common) is peaceful (1/10). This modest difference means Angelicus Pleco L073 may occasionally assert dominance over Goldfish (Comet / Common).

Angelicus Pleco L073 and Goldfish (Comet / Common) 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: Angelicus Pleco L073 is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

There is no temperature overlap between Angelicus Pleco L073 (26–30°C) and Goldfish (Comet / Common) (10–24°C). This fundamental mismatch makes long-term cohabitation impractical.

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 5–15 dGH. Regular testing will ensure conditions stay within this range.

To house Angelicus Pleco L073 and Goldfish (Comet / Common) together, plan for an aquarium of at least 200 litres with a minimum length of 120 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: Driftwood (Digestion/Hiding), Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

Angelicus Pleco L073 and Goldfish (Comet / Common) 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.

Feeding time deserves special attention with this pairing. Goldfish (Comet / Common) is an aggressive eater that may prevent Angelicus Pleco L073 from getting enough food.

Because Goldfish (Comet / Common) is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Angelicus Pleco L073 receives an adequate share.
