Behaviour & Temperament

False Glass Catfish is a peaceful species (2/10), while German Blue Ram is generally mild-mannered (4/10). This modest difference means German Blue Ram may occasionally assert dominance over False Glass Catfish.

False Glass Catfish and German Blue Ram both frequent the Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

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 False Glass Catfish and German Blue Ram to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.

Water Parameters

The safe temperature window for both species falls between 27°C and 28°C. Aim for the midpoint of this range (around 27.5°C) for optimal comfort.

Both fish can tolerate a pH between 5 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 1–8 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house False Glass Catfish and German Blue Ram together, plan for an aquarium of at least 110 litres with a minimum length of 90 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, Plants - Floating, Leaf Litter/Blackwater, Sand (Sifters), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Why This Pairing Needs Extra Planning in Practice

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. False Glass Catfish and German Blue Ram need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

Frequently Asked Questions

Can False Glass Catfish and German Blue Ram live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 110 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do False Glass Catfish and German Blue Ram need?

A minimum of 110 litres (tank length at least 90 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 False Glass Catfish and German Blue Ram together?

Keep the aquarium between 27°C and 28°C. A target of around 27.5°C sits comfortably within both species' preferred ranges.

Are False Glass Catfish or German Blue Ram aggressive?

False Glass Catfish is peaceful (2/10) and German Blue Ram is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do False Glass Catfish and German Blue Ram need?

Both species overlap in the 5–7 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

How do I manage German Blue Ram's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives German Blue Ram 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.
