I named all my bettas, when I kept them.
My first betta I called Max (beta-max, get it?)
I also had Sam and Steve.
I had an apple snail named Bob, because he just bobbed on the surface for the first week.
Currently I have four platies. Two red comet, male and female named Fred and Wilma.
The other two are some colour variation that I didn't identify. The male is dark green, almost black, except for a peach coloured spot around his mouth/face, we called him Batfish (because he looks like he's wearing a Batman outfit). The female is a pale yellow with some calico-type spots so we called her The Joker (to go with Batman, and it looks like she's wearing a bad makeup job).
We had a pearly white platy named Casper, but she recently died
My girlfriend was upset because she was her favorite.
I have many fry, which aren't named yet, except for the largest one which we named Henry P. Wigglesworth. Hopefully "he" will be a male.
I never named my emerald cories, b/c I can't tell them apart
