Does anyone else get that phrase from people? My roommate [and best friend] says this to me all the time about Admiral Finns. [Simply because I have to keep buying stuff for him... he can be such a sick little boy] It's as if she doesn't want me to take proper care of him!
This phrase just drives me crazy! Fish are pets like a cat or a dog, so I don't see why people think they're so expendable or easily thrown away.
I once had a fantail goldfish for about a day or two and he mysteriously died on me [no sign of illness] and I cried almost all day about it. I don't understand how some people can be so insensitive about our fish babies. :(
