So my sweet little fishy, Cass, is a heavy glass surfer. Whenever you come over and talk to her, she starts glass surfing like nuts and blowing bubbles and opening and closing her mouth like she's trying to talk. Problem is, I got her a new decoration. It's mock bamboo (rubber-ish) around wire, so you can bend it. It's all twisted and pretty inside her tank.
The problem is, whenever someone isn't by her tank, she just chills out in the little, completely empty area, flitting about. If you come over and say hi, she starts looping her way through the faux-bamboo, and doing her usual glass-surfing...
1. Is glass surfing so much normal?
2. Is it normal for a fish to act so differently when people are around?
3. Should I be worried about her not swimming all over unless people are around?
4. Should I return the new decoration?
