Well, yesterday, I had bought a new Betta. He was a halfmoon double tail male. Unfortunately, I had to return him as he was much too aggressive to my tetras. :( However, while checking out the fish store, I decided to try another Betta. He was advertised as a halfmoon but I think he may be more of a delta (though I am no expert at all
when it comes to this). He seems to be okay with the fish. In the beginning, he would give a little charge if a fish got in his way, but even that has seemed to decrease a bit. The picture doesn't do his color any justice, but I thought I'd give it a try anyways.
If anyone out there knows his type (halfmoon/delta/?), please let me know... :)
