I came home from a week's vacation to find my husband's fire eel with white spots aaall over it (husband is gone for months so I'm looking for help). It hadn't eaten all week. It ate the earth worms I fed it upon my return. It's living in a 120 gallon tank with 2 rope fish, 1 ornate?, other long narrow shaped fish, 1 elephant face, 1 ghost knife, 2 (though I remember having 3 when we left!) african clawed frogs, and 5 silver dollars. The heater broke while we were away and the the temperature is now around 78 C. Given this info, can anybody help me out? I might be able to get the names of the other fish if it's important. I appreciate any assistance.
