A peaceful World

Normally such a peaceful environment, I can sit and watch the fish in my tropical tank for hours. I'm fascinated by the behaviours of them. Some people go for bright colours and false looking ornaments in their tanks whereas I have chosen the more natural look and to make the fish feel like they are in their own original environment.
I say normally a peaceful environment because the filter is being rather noisy today, it's on it's way out. Time for a new one I feel but it's still not putting me off watching them closely.
