Ok, here goes...
Maui- His blue and red coloring reminded me of water and sunsets and big red flowers. Basically, I got a tropical vibe from him.
Feng- I had a hard time naming him and his tank is decorated in a kind of oriental theme. So when my cousin first saw it, he said I had done "feng-shui" on his room, so I named him Feng!
Puddles- Again, I had a hard time naming him and he is in my smallest tank, a 3 gallon. I happened to be reading about how bettas supposedly lived in puddles and well, the name stuck.
Dagger- He is an all-black crowntail with a bit of metallic gold coloring in his fins. (Here's where it gets kinda nerdy) When he swims, he reminds me of those creatures from Legend of Zelda Twilight Princess... And I wanted to give him a badass name. The tips of his fins look like they are sharp, so I called him Dagger.
Picasso- He is white with splashes of red and when I saw him, the red reminded me of paint. Picasso was the first artist that popped into my head after thinking it looked like paint.
Monkey- This one is pretty simple. He has a flesh colored face (believe it's called piebald?) Anyway, I bought him from Aquabid and the description on him said he was a monkey face. So, he is now Monkey.
Nate- I had been trying hard to think of a name for him, but was failing. Then I went to a Pink concert and she did the duet with Nate Ruess from fun and I have loved him forever, since he was the singer in The Format. So I thought, hmm... Nate would be a good name for my unnamed fish. Then I finished decorating his tank and thought how it looked so pretty Nate Berkus could have designed it, and well, now he has to be called Nate.
My mind works in crazy ways!!
