Description
The Red Terror Cichlid (Cichlasoma festae or Amphilophus festae) is a striking and aggressive South American cichlid known for its vibrant coloration and dominant personality. Here’s a detailed breakdown of its origin, care requirements, and suitable tank mates:
๐ Origin
-
Native to: Rivers and streams of western Ecuador and northern Peru, particularly in the Rio Esmeraldas basin.
-
Habitat: Found in warm, slow-moving to moderate-flow freshwater environments with rocky substrates and submerged wood.
-
Often confused with the False Red Terror (Amphilophus labiatus or Mesoheros festae), but Cichlasoma festae is the true Red Terror.
๐งช Care Requirements
| Parameter | Ideal Range |
|---|---|
| Tank Size | Minimum 75 gallons (284 L) for a single adult; 125+ gallons for a pair |
| Temperature | 24โ28ยฐC (75โ82ยฐF) |
| pH | 6.5โ8.0 |
| Hardness | 4โ15 dGH |
| Diet | Omnivorous โ high-quality pellets, frozen/live foods (shrimp, krill, worms), vegetables (peas, spinach) |
| Behavior | Territorial, very aggressive โ especially during breeding |
| Aquascape | Use rocks, caves, driftwood for territories. Secure all decorations โ they dig heavily. |
| Filtration | Strong filtration and regular water changes are essential due to heavy bioload |
๐ค Tank Mates
Tank mates must be large, robust, and able to defend themselves. Avoid small or peaceful fish. Best results are often in species-only setups or with other aggressive cichlids.
Possible Tank Mates (in very large tanks):
-
Oscar cichlids
-
Jaguar cichlids
-
Green Terrors
-
Texas Cichlids
-
Plecos (large species like Sailfin or Common)
-
Silver Dollars (fast and schooling, but risk remains)
โ ๏ธ Important: Even compatible species are at risk. Monitor closely and be ready to separate if needed.
๐ด Fun Fact
The name โRed Terrorโ comes from both their fiery red coloration (especially in females) and their extreme aggression, especially when guarding eggs or fry.
