Hi this is my first new topic started but I think it's a worthwhile one... I was wondering what your opinions on using bulbs or tubes which provide UV (usualy intended for reptiles) instead of florescent lighting would be. It seems that the majority of people who keep goldfish here in the UK keep them in indoor aquaria, and I have heard that exposure to natural sunlight improves fish colouration so why not use these lighting system instead of 'standard' models. I work in an LFS where I keep around 1000 fish altogether but my department also has tube lighting which covers 2.0, 5.0 and 10 UV intensity, if you guys think that it is a good idea to use them I will give one a go (I was thinking the 5.0 - rainforest equivalent) and photograph and colour or health changes in the fish.
