henward Posted June 5, 2012 Report Share Posted June 5, 2012 look, recently as a natural 'questioner of the status quo' - i have questions the merits and science behind TANNING AROWAWAS. does it work? i cant tell as i only have one. does anyone have any articles, info, etc of UV rays changing the colours of fish to be more vibrant? not just arowanas, but other fish too.

David R Posted June 5, 2012 Report Share Posted June 5, 2012 Its pretty easy to see how natural sunlight improves the colour or red/orange goldfish in a pond vs tank, so I guess it would apply to other fish too. Those fish in pics people like Koji post of big aro breeders being pulled out of the ponds always look really nice, and you know they haven't had artificial lighting on them...

henward Posted June 5, 2012 Author Report Share Posted June 5, 2012 yeah but im thinking, is it the maturity of the fish taht does it? i guess just open to discussion lol wondering other peoples take on it. Quote Link to comment Share on other sites More sharing options...
GrahamC Posted June 5, 2012 Report Share Posted June 5, 2012 Pigmentation in response to UVA/B is a defence against UV induced DNA damage so UV lighting will increase the fish colour. Furthermore some fish are said to have reflectance in the UV range which increases their sexual attraction. Presumably this only happens in fish which live in the zone that experiences UV radiation. http://biology.unm.edu/biology/kodric/P ... tterns.pdf Quote Link to comment Share on other sites More sharing options...

I know what you mean but it's not exactly very scientific to compare a pond to a tank and say that sunlight is the only difference that could affect fish colour. :slfg: Henward why don't you install one of those Solar Tubes in your shed to shine sunlight directly on top of Brutus?

Most of it if not all. just interesting, i guess im questioning the rationale behind arowana tanning but when you see aros in ponds, its pretty hard to not be convinced, the redness is way more extreme. a thought came to me the other day.... outdoor pond during summer.... wonder how hard it would be to heat it during summer lol Quote Link to comment Share on other sites More sharing options...
Ira Posted June 5, 2012 Report Share Posted June 5, 2012 a thought came to me the other day.... outdoor pond during summer.... wonder how hard it would be to heat it during summer lol Up in jafaland? Probably not particularly hard. Hundred meters of black irrigation pipe coiled up on the roof in the sun would do a pretty good job. Might be easier to get a couple of tanning bed lights and throw them over the tank. Quote Link to comment Share on other sites More sharing options...

henward Posted June 5, 2012 Author Report Share Posted June 5, 2012 My aro is now spooked by the lights , very strange :-? most likely it could be from external source. a red light from a tv or something can freak them out. blacked the sides and back? that helps.
