My wife & I have 3 beta's. Two males, one named Wilbur, and one named Speed Racer, and one female; Charlotte. In the tank with the female we have 3 peal danio's, and 1 striped danio. The pearl danio's are named Slim (the fat one), Chester (like the Cheeto's cheetah), and SpongeBob. Chester & SpongeBob are yellow... SpongeBog has exactly horizontal stripes on his belly fin, Chester has ones that are parallel to his body. We also have a zebra danio named stripes. In that tank we also have a Pimelodella Angelicus Catfish that is about 8" long.
