In the aquarium it needs water at 21°C (70°F). Pink salmon care at a glanceTemperature21°C (70°F) BiologyAn anadromous species which inhabits ocean and coastal streams. Epipelagic. Pelagic at the sea. In freshwater, lives in montane and piedmont rivers with moderate to fast current and gravel bottom. Spawns in riffles or at head of riffles in shallow water with current up to 1.5 m/s, and clean coarse gravel. Spends 18 months at sea after which spawning migration to the natal river or stream occurs; but because the species is less certain of its homing and there is a certain degree of wandering, streams as much as 640 km from natal streams may be used. Upon emerging from the gravel, fry immediately move downstream and remain inshore for a few months before going out to sea. Fry may feed on nymphal and larval insects while in fresh water, but may not feed at all. In the sea, young feed on copepods and larvSource: FishBase, licensed CC BY-NC 4.0.
