pt their yolk bag also have a gular sac (presumably in case of oxygen deficiency in water).
In 12 days the larvae starts feeding. Brine shrimp can be used as its first food. Small portions of food should be put in several places of the tank 5-6 times a day.
The juveniles grow fast – during the first month they grow to be about 4.5 cm long and at the end of the second month that are about 7 cm long. When growing fire eel juveniles you should turn of the filter to prevent them from getting injured if they get there.
Daily water renew (up to 10%) is a must. As a precaution you should disinfect the water with methylene blue (1-3 mg/l), antibiotics (up to 10 mg/l). Metabolic byproducts as well as food leftovers have to be removed as fast as possible. That’s why tanks without any bottom substrate will be a good idea in this respect.
Fire eel juveniles can be also put into ornamental tanks with bottom substrate layer that doesn’t exceed 3 cm. At that you have to turn the bottom substrate at least once in a month.
Using undergravel filters is possible only in case if false bottom is thoroughly fitted and there are not slits. At the age of two weeks the juveniles start getting their coloring – first the spots and lines appear and then the body gets darker.
