Can Amano Shrimp and Marble Goby Live Together?

Amano Shrimp is a peaceful species (1/10), while Marble Goby is semi-aggressive (7/10). This notable difference means Marble Goby may occasionally assert dominance over Amano Shrimp.

Large aggression gap (6 points) between Amano Shrimp and Marble Goby increases stress risk for the more peaceful fish.

Amano Shrimp and Marble Goby 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.

There is a critical concern: the Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

Worth noting: Marble Goby 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.

The safe temperature window for both species falls between 22°C and 28°C. Aim for the midpoint of this range (around 25.0°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 5–14 dGH. Regular testing will ensure conditions stay within this range.

To house Amano Shrimp and Marble Goby together, plan for an aquarium of at least 600 litres with a minimum length of 180 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: Established Algae (Otocinclus), Plants - Densely covered, Sand (Sifters), Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels). 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.

Amano Shrimp and Marble Goby 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. Marble Goby is a known shrimp eater and may prey on small invertebrates or nano fish like Amano Shrimp.

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