I also have two of these amazing fish. However, I bought one about 3 years ago from a pet store calling it a "Polypalmus fish", which I am not positive now that it is a true Palmus, or if it is a sub species. I'm not overly familiar with their background, but was enthralled with the fish. Originally he(?) was in a 30 gallon, but is now in a 55. The other I think is a Senegalis (I know it aint spelled right LoL), but I bought it at PetSmart under the guise of "dinosaur eel". I knew it was a relative of the one that I've got, but the coloring is different, however that may be due to age.
The older one is probably 3 and a half years old, the other is not quite a year yet, though they are getting close in size.
Here is a picture of the older one. He is about 7 inches long. My digicam is charging, once it does, I'm going to try to get a picture of the younger one (about 4 inches long). Hopefully we can correctly identify them?
Thanks!
