Thanks everyone.

at the moment I don't think I have been bitten by the betta bug
I'm quite happy with these two boys.

But if I am going to get another one (I'm not saying I am ) it will hopefully a CrownTail or a HalfMoon but I will have to look for them online as my local fish shop only sell veiltails.

Here is a close up picture of Colin.
His body looks a bit bent because he was going the other way, nothing to worry about.
His fins are so much better now
