Below is a picture of the second betta, a lavender and green pastel betta.
This betta is younger than my other one, so he has not yet reached his adult size or fin length. He is a double delta betta. He lives, like my other one, in a 2.5 gallon betta tank on the counter between my kitchen and my breakfast nook. One side is beside the other betta tank, which allows him to "profile", stretching his fins and getting some exercise. The other three sides are clear, allowing him to get some needed privacy or watch what is going on outside his tank.
On one side is my kitchen sink, and whenever I am working at the sink, he wants to watch what I am doing. Here he is, swimming among the castle "ruins" and plant in his tank, to keep an eye on me.
