Possible with Caution

Keeping Bolivian Ram and Red Terror (Festa's Cichlid) together is possible but requires caution due to differing aggression levels and potential behavioral clashes. Provide a spacious tank of at least 450 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Bolivian Ram and Red Terror (Festa's Cichlid)?

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

Bolivian Ram is a generally mild-mannered species (4/10), while Red Terror (Festa's Cichlid) is highly aggressive (10/10). This notable difference means Red Terror (Festa's Cichlid) may occasionally assert dominance over Bolivian Ram.

Large aggression gap (6 points) between Bolivian Ram and Red Terror (Festa's Cichlid) increases stress risk for the more peaceful fish.

Bolivian Ram and Red Terror (Festa's Cichlid) both frequent the Bottom (Substrate) and 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.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks.

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 Bolivian Ram and Red Terror (Festa's Cichlid) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

Water Parameters

The safe temperature window for both species falls between 25°C and 28°C. Aim for the midpoint of this range (around 26.5°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 4–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Bolivian Ram and Red Terror (Festa's Cichlid) together, plan for an aquarium of at least 450 litres with a minimum length of 150 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), 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. Bolivian Ram and Red Terror (Festa's Cichlid) 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Bolivian Ram and Red Terror (Festa's Cichlid).

Frequently Asked Questions

Can Bolivian Ram and Red Terror (Festa's Cichlid) live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 450 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Bolivian Ram and Red Terror (Festa's Cichlid) need?

A minimum of 450 litres (tank length at least 150 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 Bolivian Ram and Red Terror (Festa's Cichlid) together?

Keep the aquarium between 25°C and 28°C. A target of around 26.5°C sits comfortably within both species' preferred ranges.

Are Bolivian Ram or Red Terror (Festa's Cichlid) aggressive?

Bolivian Ram is generally mild-mannered (4/10) and Red Terror (Festa's Cichlid) is highly aggressive (10/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Bolivian Ram and Red Terror (Festa's Cichlid) need?

Both species overlap in the 6.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

How do I manage Bolivian Ram's territorial behaviour?

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