I have a 4 inch rhom that I've had since January. I thought he would never swim around when I first got him. Starting last month, he has been swimming around constantly. He is in a high traffic area and he has been getting used to people.
About three weeks ago, I put my finger up against the glass and he swam over real quick and tried to bite it through the glass. I was shocked.
Although, he hasn't done it since....until a few minutes ago. The past few days while I have been sitting by his tank, I have been placing the tip of my finger on the glass and moving it really slowly. He normally starts shaking and fluttering his fins. Well, today, he attacked my finger twice. It was pretty cool.
He has been getting more daring the past month and I am guessing that he will continue to do that.
Does anyone else have experience or comments to share about this?
