Behaviour & Temperament
Both Alligator Pleco and Checkerboard Cichlid are generally mild-mannered species with an aggression score of 3/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.
Alligator Pleco and Checkerboard Cichlid 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.
Worth noting: Alligator Pleco is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
Water Parameters
The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.
Both fish can tolerate a pH between 6 and 6.5. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 4–5 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Alligator Pleco and Checkerboard Cichlid together, plan for an aquarium of at least 280 litres with a minimum length of 120 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: Driftwood (Digestion/Hiding), Established Algae (Otocinclus), Sand (Sifters), Leaf Litter/Blackwater, Plants - Densely covered. Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Alligator Pleco is a plant destroyer, which conflicts with Checkerboard Cichlid's requirement for live plants. Compromise where possible or prioritise the more critical need.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

What pH do Alligator Pleco and Checkerboard Cichlid need?
Both species overlap in the 6–6.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Does Alligator Pleco being nocturnal affect compatibility?
Alligator Pleco 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 Alligator Pleco during evening hours.
