I was wondering if anyone keeps/has kept Trochilocharax ornatus (aka crystal rainbow tetra/hummingbird tetra)? I’m intrigued by their delicate beauty and thought they’d make a good addition to my 75 gallon aquarium. The little information I can find about them from the web suggests that they are rather sensitive. A couple of folks have mentioned a tendency for parts of their clear bodies to turn opaque. They die shortly after that. Any info would be greatly appreciated.
