Okay so I have a dinosaur bicher and an Oscar in a tank together and the bicher constantly follows the oscar around swimming side by side connected to him kinda rubbing his head on him ha. Both fish seem to be healthy and it doesn't seem to bother the oscar as he does not try and I swim away like he is being attacked. Both fish are juveniles if that matters. And neither fish is rubbing against other decorations or anything in the aquarium and look healthy. Anyone know what this behavior is about?
