Description: Tetraodon lineatus has a greenish body coloration with yellow stripes running down its body. The belly is yellow. Young Fahaka Puffers show mottled coloration without strong colors and may be confused with several other freshwater puffers. Juveniles develop mature coloration gradually, with some yellow stripes appearing on the flank. They can also change their color depending on their mood or surroundings, as they try to reduce contrast between themselves and their surroundings. Stressed fish are likely to appear darker than normal. Puffers have the ability to inflate their stomachs with air or water. The fish becomes 2 or 3 times its normal size, big enough to scare away many potential predators. Nile Puffers have beak-like mouthparts, which are formed by a fusing of 2 teeth from each jaw, where they get therir latin name (Tetraodon). This species is very sensitive ammonia and nitrites, and since they are messy eaters, so over filtration and regular partial water changes are a must.
The identification of sexes is very difficult, the female’s belly becomes rounder. The Fahaka puffer is a very hard species to breed, mainly due to its aggressive temperament. Tetraodon lineatus become sexually mature at around 12 months of age. Just before spawning the female’s small ovipositor become visible. During breeding the male and the female will swim together for a short time, than the male grips onto the underside of the female, At this point the female will release the eggs and the male will fertilise them. They will usually repeat this process for several times. Several thousand eggs may be deposited in this way! The eggs sink to the substrate and the parents should be removed. The eggs hatch in 72-96 hours, and the water level should be lowered to only 5-10 cm, as the fry need access to the surface. They become free swimming after a week, and require tiny live foods. Large losses due to starvation are common at this point. The fry become aggressive from an early age, and should be separated regularly.
