I bought a baby Betta from Petco and this is the first time I have cared for a Betta this young. When I got him, he was the smallest of all the babies. I've had him for roughly a month now. His fins have always been red and earlier this week he has been showing some blue along the edges. However his body is "skin colored" as my boyfriend puts it. I'm not sure if this is what color he's going to be or if all babies start off as this yellow-ish tan and then develop other colors.
And in other news, I watched him blow a bubble nest today and I'm thoroughly confused. XD I thought he was too young for that but I guess he thinks otherwise.
