What is your water ph and hardness? My lfs had the species you have and has another type of african eel, Mastacembalus elipsifer. I really want to get it but I don't have the tank space right now but in a month or so I will. Besides the bottle technique for feeding, do have any other tips?
Its been a while since I tested hardness so I am not sure right now. My ph is about 7.8.
No other tips really, pretty easy to take care of once you get a good method of feeding them.
I am not sure on the maximum potential size of the plagiostoma, there seems to be conflicting info about that. Mine is about 10" and hasn't grown in probably 6 months, I think 12" would be about max.
