The Lousielle Cichlid is not a widely recognized species name in the cichlid-keeping community or scientific literature. It’s possible that you may be referring to one of the following:
 
A misspelling or trade name of another known cichlid species (e.g., Louiselli, Loiselii, or similar).
A local or hybrid variant sold under a trade name.
Possibly Parachromis loisellei, a real and popular species in the aquarium trade.

Minimum 75 gallons (284 litres) for an adult.
Larger if kept with tankmates or in breeding pairs.
 
 
 
🌡️ Water Parameters:
 
 
Temperature: 24–28°C (75–82°F)
pH: 7.0–8.0

Fine sand or gravel substrate.
