I recently purchased a male n female Apisto and the female died same night. I took her back got a new one. She lasted for a week and he was trying to follow her around constantly and she died 4 days ago and he has changed. Hides all the time, doesnt really eat anymore and just is sadddddd. Can loneliness happen and possibly lead to his death? I have 3 stores looking for a female RN, but because of Corona, some arent taking fish shipments for now. What do i do? ANY INFO WILL BE APPRECIATED!!!
