I just bought one of this babies, I really didn't know anything about this fellas, but the girl i bought her from (I feel like she is a baby girl), told me she was freshwater, but then I made my research and it seems she's not!! I don't know what to do, I'm quite new to these beautiful creatures, I don't wanna lose her, I'm willing to buy a new tank just for her but I don't know what she needs, she has been living with an Oscar, a Green terror and a Firemouth, they all get along, but Khaleesi (my eel) is acting weird today, she has been laying with her belly up, she has never done this before!!, she still swims every now and then and acts kinda normal (for her), but the laying upside down is quite disturbing.
She usually is very friendly, she actually seeks my hand when feeding them and she likes being held.
Can anyone please explain me what is going on and what can I do to make her happy again??!
THANKS
