Nice crew Charney, I've got 6 now that I've caught. Have seen some interesting things with these in the wild. Firstly, when you find one, you usually find a few more in very close proximity. One night we uncovered about 10 living in an area about 6ft squared, ranging from 6" up to 4ft. I have seen them from electric yellow base through to a really nice red. Mine are still in the 6x2x2 holding tank with kuhlia marginata and rupestris. I keep the tank half full with no gaps in the lids, these guys like all eels are incredible escape artists and when you see the gaps even big guys can squeeze into...
Water is full fresh, coral is because our water here is super soft. When these guys are caught the produce excessive amounts of slime which seems to kill any other fish in the collecting tub...something to consider when adding one to a tank. Probably feed predominantly on macrobrachium sp in the wild (long armed shrimp), in the aquarium they are pretty proficient hunters of shrimp but have never seen them get close to grabbing a fish (unless the fish has a chunk of prawn in its mouth and the eel homes in on it!
Remind me to post up the water params of the creeks where we find these guys. Also I will upload a paper on them by Ebner. I will probably see him in the next few weeks and see if he has begun the otolith work to determine their movements (if any) between fresh and brackish/marine waters. If I think of anything else will post it up or any questions, feel free to ask.
