The new “Gamma Ray” Tube light makes sure your Arowanas gets light that simulates UVB and UVA light emitted by the sun. Arowanas need both UVB and UVA light to live healthy lifestyles. These are both types of ultraviolet (and UV) light. Each type of light has a different role to play in keeping your arowana happy and healthy.
• UVA light helps regulate behaviors such as feeding, movement, mating and similar activities. It can cover the surface of the arowana skin by its relatively short wavelength, thereby increasing the effective color area of the arowana.
• UVB light allows the synthesis of arowana scales, which helps to absorb calcium.
Make sure that UVB bulbs are used during the day and turned off during the night to mimic daytime and nighttime. Every type of reptile or amphibian has slightly different needs but a general rule of thumb is to keep the UVB light/heat source on for 12 hours and off for 12 hours, with the built-in timer programmable between 8,12,16 and 24 hours.
We also offer an adjustable mounting clip for your lamp so you can submerge the lamp or mount it outside your tank at your desired level, you can also mount multiple lights with a single clip!
