I always just find with most pets that you are choosing from a group that one always chooses you, not the other way around. If the last one speaks to you that's the one you should get!
The second boy, the CT, looks like he has the same color scheme as my favorite boy (my avatar pic) who passed away over night :'(
When I saw him in Petsmart I knew there was no way I was leaving without him, and it wasn't JUST his looks, because I've turned down others, it's just SOMETHING. And my baby betta, I convinced myself not to buy him, and ended up going back 2 hours later to get him! You just know when you find the right one.
