Can Indian Glassfish and Pacific Sturgeon Live Together?

Indian Glassfish is a peaceful species (2/10), while Pacific Sturgeon is generally mild-mannered (3/10). This modest difference means Pacific Sturgeon may occasionally assert dominance over Indian Glassfish.

In terms of spatial distribution, Indian Glassfish prefers the Middle (Open Water) zone, whereas Pacific Sturgeon occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

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.

To improve the chances of a peaceful coexistence in this community tank: 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 20°C and 22°C. Aim for the midpoint of this range (around 21.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 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 7–20 dGH. Regular testing will ensure conditions stay within this range.

To house Indian Glassfish and Pacific Sturgeon together, plan for an aquarium of at least 20000 litres with a minimum length of 600 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 — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Plants - Densely covered, Sand (Sifters), 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.

Feeding time deserves special attention with this pairing. Pacific Sturgeon is an aggressive eater that may prevent Indian Glassfish from getting enough food.

Because Pacific Sturgeon is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Indian Glassfish receives an adequate share.
