Temperament and Behavior
Behavior
Golden Wonder Killifish are known for their active and lively behavior. They are excellent jumpers, so a well-fitted aquarium lid is necessary.
They are generally peaceful, but males can display territorial behavior and may exhibit aggression towards other males, especially when breeding.
Breeding
Breeding Golden Wonder Killifish can be challenging as they require specific conditions. It's best to set up a separate breeding tank with suitable spawning materials like fine-leaved plants or mops.
The female will lay adhesive eggs among the plants, which should be promptly removed to a separate rearing tank or incubation medium to ensure survival.
Compatibility
Golden Wonder Killifish can be kept with other peaceful fish species that are similar in size. Avoid keeping them with fin-nipping or aggressive fish that may stress or harm them.
Compatible tankmates include peaceful tetras, rasboras, gouramis, and some peaceful dwarf cichlids. However, always monitor the behavior of tankmates to ensure compatibility.
Tankmates
Avoid keeping Golden Wonder Killifish with small, delicate fish or slow-moving species that may become targets of their aggression or lively behavior.
Consider tankmates that inhabit different areas of the aquarium, such as middle or top-dwelling fish, to utilize the full space and minimize territorial conflicts.
Activity Level
Golden Wonder Killifish are highly active swimmers and appreciate open spaces for swimming. They will explore the tank and may chase or display courting behavior towards other fish, particularly during breeding periods.
Clean up Crew

Select Breeding Pair: Choose a compatible breeding pair of Golden Wonder Killifish. Ideally, select a male and female that are healthy, mature, and show signs of readiness for breeding, such as vibrant coloration and active behavior.
Introduce the Pair to the Breeding Tank: Transfer the selected breeding pair to the prepared breeding tank. Ensure that the tank environment closely matches their preferred conditions.
Stimulate Breeding Behavior: To encourage breeding behavior, you can provide visual cues like mirrors or transparent dividers that allow the male to display his vibrant colors and court the female. Maintain consistent water parameters and ensure that the fish have a suitable diet to promote breeding readiness.
Observe Courtship and Spawning: Golden Wonder Killifish engage in courtship displays before spawning. The male may display vibrant colors, flare his fins, or perform dance-like movements to attract the female. Once courtship is successful, the female will lay adhesive eggs on suitable spawning materials.
Remove Spawning Materials: After the female lays eggs, promptly remove the spawning materials from the breeding tank to prevent the parents from consuming the eggs. Transfer the eggs to a separate incubation medium or a separate rearing tank for further development.
Incubate and Raise the Fry: Transfer the eggs to the incubation medium, such as peat moss, or use specialized incubation techniques recommended for Golden Wonder Killifish. Maintain appropriate temperature, moisture, and conditions for the eggs to hatch. Once hatched, feed the fry small, nutritious foods such as infusoria, baby brine shrimp, or commercially available fry foods.
Provide Proper Care and Tank Conditions: As the fry grow, ensure they have a suitable environment with clean water, appropriate food, and sufficient space to develop. Gradually transition them to larger food options as they mature.
Monitor Growth and Development: Regularly monitor the fry's growth and development. Pay attention to their health, behavior, and water conditions. Make necessary adjustments to their diet and tank setup as they grow.
