I got my Betta for my birthday and had set up the 5 gallon tank that morning. the tank still had bubbles all over the inside of the glass in spite of the fact that the water had been well treated with Stresscoat. I didn't wait to put him in his tank because the water in the container from the pet store was so grungy. Now he has small white scars like burn scars on the outside of one of his gills. He has had one course of antibiotics and seems to be doing fine, but did I burn him? Is this something else that needs attention? The tank is already at the seasoned stage as I have used an agent to help the process along and it didn't take as long. ???
