Can Leopard Frog Pleco (L134) and Royal Pleco (L190) Live Together?

Possible with Caution

Keeping Leopard Frog Pleco (L134) and Royal Pleco (L190) together is possible but requires caution due to 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.

Behaviour & Temperament

Leopard Frog Pleco (L134) is a generally mild-mannered species (3/10), while Royal Pleco (L190) is moderately assertive (5/10). This modest difference means Royal Pleco (L190) may occasionally assert dominance over Leopard Frog Pleco (L134).

Leopard Frog Pleco (L134) and Royal Pleco (L190) 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.

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

Worth noting: Leopard Frog Pleco (L134) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

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 Leopard Frog Pleco (L134) and Royal Pleco (L190) 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 26Β°C and 28Β°C. Aim for the midpoint of this range (around 27.0Β°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 7.4. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Leopard Frog Pleco (L134) and Royal Pleco (L190) 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 β€” caves, driftwood, and dense plant clusters β€” so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), Sand (Sifters). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Leopard Frog Pleco (L134) and Royal Pleco (L190).

Frequently Asked Questions

Can Leopard Frog Pleco (L134) and Royal Pleco (L190) 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 Leopard Frog Pleco (L134) and Royal Pleco (L190) 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 Leopard Frog Pleco (L134) and Royal Pleco (L190) together?

Keep the aquarium between 26Β°C and 28Β°C. A target of around 27.0Β°C sits comfortably within both species' preferred ranges.

Are Leopard Frog Pleco (L134) or Royal Pleco (L190) aggressive?

Leopard Frog Pleco (L134) is generally mild-mannered (3/10) and Royal Pleco (L190) is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Leopard Frog Pleco (L134) and Royal Pleco (L190) need?

Both species overlap in the 6.5–7.4 pH range. Consistency is key β€” avoid sudden swings, and test regularly to stay within this window.

How do I manage Leopard Frog Pleco (L134)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Leopard Frog Pleco (L134) space to claim a territory without encroaching on the other fish's area. Adding dΓ©cor that divides the tank into distinct zones works especially well.

Does Leopard Frog Pleco (L134) being nocturnal affect compatibility?

Leopard Frog Pleco (L134) is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Leopard Frog Pleco (L134) during evening hours.
