Nice, right?
Well, two days later, clear on the other side of town, I found his identical twin!
So, naturally, I adopted him too! If you look closely, the only difference is actually the color that is at the base of the tail. The first one has blue "creeping" on to his tail, the second one has red!
They're both called "Twin" because that's about the only names I could think of. I rarely name my fish anyway.
