Thank you very much, it always helps knowing what you have in order to properly take care of them. They sold him as a freshwater eel, not brackish. So I’m having a delema now. Should I take him back or keep him. I have him with my two peacock bass (which are not brackish). Can’t put him with my Jaguar or he will surely be killed, and don’t feel comfortable with putting him in the other tank with my stingray/arowana.
