Can Red Goldflake Shrimp and Smallmouth Bass Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Red Goldflake Shrimp and Smallmouth Bass are not recommended as tank mates due to no temperature overlap and piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Red Goldflake Shrimp and Smallmouth Bass?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

Red Goldflake Shrimp is a peaceful species (0/10), while Smallmouth Bass is semi-aggressive (7/10). This notable difference means Smallmouth Bass may occasionally assert dominance over Red Goldflake Shrimp.

Large aggression gap (7 points) between Red Goldflake Shrimp and Smallmouth Bass increases stress risk for the more peaceful fish.

Red Goldflake Shrimp and Smallmouth Bass 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: Aggressive fish may bully and stress shy, slow-moving species. Hyperactive swimmers can stress shy, slow-moving species through constant motion. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

Worth noting: Smallmouth Bass is a known jumper, so a tight-fitting lid is essential.

Water Parameters

There is no temperature overlap between Red Goldflake Shrimp (26–29°C) and Smallmouth Bass (15–25°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7.5 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Red Goldflake Shrimp and Smallmouth Bass together, plan for an aquarium of at least 680 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: Sand (Sifters), Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

Red Goldflake Shrimp prefers Low (Still Water) flow while Smallmouth Bass needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Why This Pairing Usually Fails in Practice

Red Goldflake Shrimp and Smallmouth Bass 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Red Goldflake Shrimp and Smallmouth Bass.

Diet & Feeding

Feeding time deserves special attention with this pairing. Smallmouth Bass is an aggressive eater that may prevent Red Goldflake Shrimp from getting enough food.

Because Smallmouth Bass is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Red Goldflake Shrimp receives an adequate share.

Frequently Asked Questions

Can Red Goldflake Shrimp and Smallmouth Bass live together?

No. This combination is not recommended. Key incompatibilities — such as non-overlapping temperature ranges — make cohabitation unsafe.

What size tank do Red Goldflake Shrimp and Smallmouth Bass need?

A minimum of 680 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 Red Goldflake Shrimp and Smallmouth Bass together?

Unfortunately, there is no temperature range that satisfies both species. Red Goldflake Shrimp requires 26–29°C, while Smallmouth Bass needs 15–25°C.

Are Red Goldflake Shrimp or Smallmouth Bass aggressive?

Red Goldflake Shrimp is peaceful (0/10) and Smallmouth Bass is semi-aggressive (7/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Red Goldflake Shrimp and Smallmouth Bass need?

Both species overlap in the 7.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

How do I manage Smallmouth Bass's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Smallmouth Bass 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.
