I just got this setup for 140 from a local pet shop. Aquatic Life Light T5 HO 4-Lamp 4-Lunar Aquarium Light, 36-Inch http://amzn.com/B001V95TGY
That sounds like a good lighting set-up for your tank. If the price is right for you, go for it.
Can someone explain the difference in caring for wild vs tank bred discus? I know the color is different but what about caring?
I also see ones from asia like thailand and singapore and some are hormoned and some are not. Whats difference and pros and cons?
That is a rather difficult question to answer.
Caring for wilds, at least initially, may prove to be somewhat more problematic than caring for domestic farm-bred fish, and dependent on the supplier, what species of wilds, and their size.
Wild discus may or may not have been properly de-wormed, for example, and may carry some pathogens that farm-bred fish would not normally carry, so a bit of a risk there. And they are more disposed to rely upon, as was pointed out in a recent post above, different water quality and conditions than domestics can, and do, readily adopt to.
Overall, I believe it's quite a bit safer to work with domestics, as opposed to wilds, for many & varied reasons. Doesn't mean one shouldn't try it - just expect the potential for a touch more difficulty keeping wilds.
As for farm-bred & raised fish, Malaysia, and Singapore to a lesser extent, are reputed to produce excellent quality fish, whereas Thailand, whether deserved or not, seems to have a current rep for supplying less than top-quality fish, with some breeders being said to use hormones to enhance coloration, etc. - not a desirable practice.
