Zebra Danios

Question
I got two zebra danios a week from today. The smaller one is doing fine eating and everything, but the bigger one seems kind of sluggish and won't eat. Now a week later the color has faded on the bigger fish. The other one is the same color. I am probably going to get some more zebra danios tomorrow. Also are glofish compatible with bettas? Thanks!

Answer
Elizabeth,
Sometimes the fish are ill when you bring them home. Some fish also take a bit longer to get used to their new homes. What is their water temperature? It sounds like the fish is a bit stressed and this could be because of the new environment. Make sure you are not over feeding and doing weekly water changes. As for the Betta, if it is a male, it is best to keep them alone. Glofish are what I call zipper fish, They are very active and go zipping through the tank. Betta's are much slower and can get stressed by having the glofish with them.
