i have to dissagree here. there are, at least a handful of morays that spend nearly their entire existences in freshwater. Gymnothorax polyuranodon is just one of them. i happen to know Nameless0 (david) very well, and know the eels he is in the process of aquireing have been in freshwater for an extended period of time, are feeding, and have grown considerably since they were purchased by their previous owner......
just my $0.02.....
