They may not know there is glass and it takes time for them to learn. If your tank glass is reflective they may think it's an enemy fish and try to attack. If that's the case, I suggest getting a clear glass tank before the fish hurts itself too much.
Fish make very good pets. They tend to run into the side of their tank or fish bowl, usually because they are not aware that it ends.
If you are talking about such a small tank that the fish is touching all sides at the same time, then yes. But if you are talking about a little goldfish in a 15cm x 15cm tank then no, it will just be a bit uncomfortable.
no filter because for smaller fish it can hurt or even kill them and for the old filter use bigger fish
Yes they can if there are items or decorations in their tank that could hurt them if they swam too close.
It is not healthy or productive to try to hurt your ex. Focus on healing and moving on from the relationship instead of seeking revenge. Engaging in actions to intentionally harm your ex will only prolong your own pain and hinder your own personal growth.
