Suddenly hiding Platie
I have had a blue Platie and a red Platie who hung together for 2 years.
Last week the blue one died and then the red one immediately started hiding!
I bought two more platies to keep him or her company, but he is still hiding...perhaps this time out of fear.
Can a fish mourn?
He eats when food falls down close to his hiding spot and when he swims in the darkened water his swimming is normal.
To make him feel more at ease and as I have no live plants, I've turned off the overhead fluorescent and given the tank indirect lighting.
Could somebody please help me with some opinions.
I'm feeling bad for him....he was so well adjusted, as are all the other community fish in the 29 gal tank.
