My goodness, do you people even know who CFC is? If anyone can house a monster like that long term, it's him. I think you all have been living under a rock, seriously.
Anyway, what is the sp. on the Gymnotus, CFC? coatesi or tigre? Lovely fish. I used to work for an ichtyologist who specialized in them. If it is a tigre, then he was actually the one who discovered it: Dr. Crampton.
