Oliver had what I'm assuming to be lockjaw last week. He was too excited when eating one day and his jaw locked shut! He can still breathe but can't eat. This went on for three days until I added epsom salt to the tank. The next day he finally ate. Not yesterday the same thing happened. He ate fine, then the next meal he couldn't open his mouth. This am he got a bite stuck and I grabbed the net to help him get it out because he panicked and he couldn't get air. But he finally got it out when I tried to net him. He wants to eat... very badly! We've tried breaking up worms (he hates worms) we tried crushing the betta bites and he can't eat them. I'm not sure what to do. I plan on adding more epsom to the tank when we get home from work. But I'm getting worried!
