Description

This description appears to reference care guidelines for a Central American cichlid, possibly a more aggressive species like a Midas Cichlid (Amphilophus citrinellus) or a similar fish. Here’s a detailed summary of the key points and care recommendations based on the provided information:

---

Tank Setup

• Decor: Use rocks and bogwood to create hiding spots and define territories.
  • Secure decor properly; these fish are known for rearranging their environment.
• Plants: Can be included but are likely to be uprooted. Consider hardy or artificial plants if using live plants.
• Lighting: Not critical but ensure adequate light for the health of tank inhabitants.
• Filtration: Provide strong filtration to handle waste, as these fish are messy eaters.

---

Water Conditions

• Temperature: 78–86°F (26–30°C).
• pH: Neutral, around 7.0.
• Hardness: 10–15°H.

---

Diet

• Wild diet: Primarily herbivorous but opportunistically omnivorous.
• In captivity:
  • Staple: High-quality cichlid pellets.
  • Protein supplements: Prawn, mussel, white fish.
  • Vegetable matter: Spirulina-based foods, algae wafers, or blanched vegetables like spinach or zucchini.

---

Behavior and Compatibility

• Temperament: Highly aggressive, especially toward conspecifics and during breeding.
• Tankmates:
  • Can sometimes coexist in a Central American cichlid community, provided there is ample space and decor to establish territories.
  • Success is not guaranteed, and fights may occur.
• Pairing: Bonded pairs can live together peacefully, but ensure the female is not bullied, especially during spawning.

---

Sexual Dimorphism

• Male characteristics:
  • Larger body size.
  • Development of a nuchal hump (a fleshy growth on the head).
  • Extended dorsal and anal fins.

---

Breeding

• Challenges: The biggest obstacle is ensuring the pair can coexist without excessive aggression.
• Spawning Process:
  • The pair will clean and prepare a spawning site (e.g., a large rock or cave).
  • Spawning can be aggressive; monitor the male’s behavior toward the female.
• Egg and Fry Care:
  • Eggs hatch in 2–3 days.
  • Fry become free-swimming approximately 4 days later.
  • Feed fry with newly hatched brine shrimp initially, then progress to microworms, specialized fry foods, and crushed flake or pellets.
• Parental Behavior:
  • Both parents protect the fry but may grow aggressive as they prepare for the next breeding cycle.
  • Remove fry to a separate grow-out tank at this stage.

This profile outlines the care and behavior of aggressive cichlid species, emphasizing the need for robust tank setups, careful monitoring of aggression, and sufficient space to minimize conflict. If you plan to keep or breed such species, ensure you are prepared for their unique challenges and rewarding interactions.
