Hello all! My oscar has been acting strange lately. He's taken to picking up rocks in his mouth and putting them in the corner. He's made a small hole all the way to the glass at the bottem and he likes to sit in it. He also gets very defensive if i go near it. He also has dimmed way down on his eating habits. I usually feed him whenever he's hungry. Normally it's 3-4 times a day, but not it's only 1-2 times a day. Does anyone know what's wrong?

Okay, so from reading others posts i guess that the digging is normal. Haha

Oh yeah it is. Its a good thing...means you have a healthy, active oscar.

This would be typical signs of breeding if you were to have a couple of Oscars. However, the way I see it is if you are keeping one Oscar on its own in captivity then it has no chance to find a mate, therefore when it's becomes fruity, i.e. sexually mature/wants to breed, it will act out the same behavior as if it had a mate. That is my theory anyway

Yay. Thanks!
