Veil Tail Bettas

Not the greatest of photos, I realise, but I wanted to show off my bettas I have four males (two veil tails and two crown tails) and one female (veil tail). These are my two veil tails for those of you unfamiliar with bettas. The yellow one's name is Casteil (my friend wanted the name because she loves Supernatural and I agreed because it's a rather nice name) and the red/mauve one is unnamed at the moment. Feel free to suggest names.
