I just bought 2 baby polypterus. One is a beautiful endlicheri that still has its external gills. The other, Im not so sure. They're both 3" long and eat well. I found them both in the same aquarium full of endlicheris at an LFS. I bought the other one because it had a different pattern, looked cool and was cheaper than the rest. At first I thought it was an ornate until I got home and got to look at it better. It doesn't seem to resemble any of the more commonly sold polypterus species. It has irregular marks(?) near its tail fin, has a longer upper jaw, and is covered by grey spots on the dorsal side. The LFS didn't know what is was either but they know what the endlichers were and referred to them as giant bichir, hence the higher price. I need help identifying it. Sorry I can't get better pictures, it keeps swimming at night and hidden the rest of the day. Thanks!
