May be fed daphnia, mosquito larvae, brine shrimp and other small live food. Will also take chopped earthworms.
This species has an extended breeding season from July to February. During this period females develop a bluish tinge on their upper sides while males develop black fins – except for the pectorals which remain clear – other dark markings become more pronounced and the sides attain an orange colour.
Pre-spawning behavior consists of the male moving in tight circles directly in front of the female, with fins held erect and rapid vibration of the body. Larger males in group situations become more aggressive towards their rivals for a few days prior to spawning.
Actual spawning is very swift. Typically, during the mid to late morning several males will drive a selected female towards the surface which will, after a few seconds of frenetic activity expel a single demersal egg of about 1.2 mm in diameter. This procedure is repeated at intervals of around 10 to 15 minutes for approximately 2 hours.
The adhesive eggs sink to the bottom and hatch in approximately 3 days at which time the larvae are only around 3 mm long. Newly hatched larvae are poorly developed with barely detectable eyes, no mouth or vent and practically no colouration. Within 28 days larval development has been completed and the young fish are around 20 mm in length.
Carnivorous, mainly feeding on caddisfly larvae but other insects are also taken from the water surface.
HOW TO INTRODUCE YOUR NEW FISH
- Always quarantine your new fish to observe health and behaviour prior to introduction to your main aquarium.
- Make sure you check your water quality before adding new fish. Do a water change if required and check pH and GH.
- Sit the unopened bag in the top of the tank and leave it for 5 to 10 minutes for the temperature to equalise.
- Open the bag and pour fish and water into a bucket. Slowly add 1 cup of tank water into the bucket. Repeat this process every 5 minutes until you have doubled the water volume in the bucket.
- After another 5 minutes take your fish from the bucket with a clean fish net and release into your aquarium. DO NOT use the water from the bucket – throw this water away.
- A prophylactic treatment of the tank with Melafix, De Stress and or a broad spectrum anti biotic treatment, can help fish overcome the stress of getting relocated which often can bring illness.
