my kids name the fish, and they are usually really unique names LOL
. The six zebra danios are, in no particular order, Speedy Bob, Speedy Bob's Wife, Speedy Bob's Brother, Uncle Speedy Bob, Grampa Speedy Bob and Nemo's Little Brother Speedy Bob. The angels are Mr & Mrs Blackie and Mr & Mrs Whitey. My daughter heard me saying the "science name" of the albino cory cats was "Corydoras" and immediately dubbed the pair Dora and Boots. The Betta's name is Fluffy, because he gets fluffy when he's excited...I thought it was a pretty unique observation. The plecos have been named variations of "smoochy" "slurpy" and other such kissy-names.
Funny story here, we had a friend over to dinner the other night, and he was fascinated with my community tank in the dining room (you can see it in the photo gallery if you care to). He asked me, in front of my 5 year old son Nathan, if I knew the names of all the fish, meaning their species.... as you can imagine, Nathan started rattling on "this one is Speedy Bob and this one is....." I laughed myself silly.
As for myself, I use "pet" names, no pun intended. I talk to the fish all the time...it's ok, they don't answer. I call them honey and sweetie, my pregnant swords usually get mama love or something, no one name, just terms of endearment.
