I was looking in Petsmart the other day and I have a question about the condition of the Betta fish that I saw. They had them in their little containers like always but the water was like a blue color. It was dark enough to hardly be able to see the fish and you couldn't really tell what colors they were or the condition they were in. I started checking them out and saw a few dead ones, some with a lot of gunk in their containers, and some just seemed like they were ok. What in the world is the blue???? I've never seen this done with any other bettas. Was the store trying to hide the condition of the fish? (Seemed like it cause you could barely see them!) Or were they being treated for something?
