Feeding points

Weakly acidic soft water is suitable for breeding, and the water temperature is 20-30℃. It is omnivorous, easy to manage for bait and water quality, and can be reared even without breeding experience. The abdomen of the mature female is enlarged, the anal fin of the male is hooked, and the caudal fin appears red. When breeding, sand the bottom of the aquarium, plant some longer plants, and the water quality is neutral. The male fish chases the female to ovulate and fertilize. Female fish can produce 300-400 transparent eggs at a time, slightly sticky, and can be attached to aquatic plants. The larvae can be hatched after 24 hours. They start swimming the next day and start feeding after 2-3 days. Rotifers, freshly hatched daphnia or egg yolk can be used.


The Bloodfin Tetras are egg layers that like their privacy during breeding. The breeding tank should have very low lighting and the water should be more acidic. In order to improve their health condition and make them able to reproduce properly, give them high-quality food that is rich in nutrients, like brine shrimp. After a few days, 300 to 500 eggs will be laid on plants with wide leaves, so make sure you provide a suitable amount of these plants. Remember to remove the parents after the female lays her eggs if you want to keep the fry.


The red-tailed glass fish has a mild temperament, likes to swim in groups, and likes to live in the middle and lower layers of water.
