I have a crown tail...basically a fancy betta. We have had him for several months. One day we got up and he was over in the corner of the tank. Which I thought was rather strange because he was always a social little bugger. Well, I looked over the internet and it was saying he was depressed. I placed him over close to the females that I have and he has not perked up. I have done water changes with aquarium salt and mellafix. None of this has worked. He goes to take a breath and he takes the air in and then bubbles back out. I am afraid to touch him, because he will sink to the bottom then come right back up. Then he sinks and lays there. I mean, I have tried all I can and I need some help because my mother really liked this one. He is not that old and was bought from a reliable pet store. His color has not faded even though he has not eaten for about 2 weeks now.

Any help will be appreciated!
