This article really got me thinking and I must admit, I do acknowledge the relationships I have developed with my fish. This is a much bigger picture of the relationships we have with other species, and with fish.  
 
"With the sentience of vertebrates now enshrined in UK and EU law, is it time we rethought our relationship with fish? If you’ve ever had a pet, visited a zoo or watched wild animals at play, it’s likely you’ve considered the concept of animal sentience. Loosely defined as the ability to experience both positive and negative emotions, such as pleasure, joy, pain and fear, animal sentience acknowledges that living creatures have feelings and awareness."
