Considering many keepers won't know if their fish are wild caught or captive bred these fish should be kept at a pH of 5.5 to 6.5. You run a very real risk of killing fish at a pH of 7. Even captive bred fish are used to acidic water. And when you consider that wild fish may be shipped from exporters in South America with very acidic water on monday, arrive at a wholesaler on wednesday, shipped to an LFS on thursday and then in your tank on thursday / friday you'll appreciate the stress that these delicate fish go through. KEEP THEM IN ACIDIC WATER if you want them to do well!
