It hard for me to vote because I need to see a picture. What colours are it? It wouldn't be good to call a betta butterfly when its dark fins are drooping down. Then again, I'm not sure, just to see a pic helps.
Ok now what i think you should do is firstly study your fish and find out its personality and the naughty things she does (e.g being a greedy pig) and then think of a name
Well after much deliberation, and carefully taking into account everyones posts, i have decided on the name Spot for my new betta girl. The reason is i wanted to observe her behavior and get to know her a bit and i came home from work tonite and there she was curled up in the little tiny clay pot in her fishbowl sleeping, just like a little puppy dog!! :kira: and so i named her Spot! hehe it was either that or Bowser and i think that Spot is much cuter, and slightly ironic because she is pure white (with a bit of iridescent blue on the tips of her fins). Anyways just thought i would follow up on this thread b/c i am totally in love with my new girlie!! nitey nite pplz! ~dEx
