I have a male Betta. I've had him for a few months now and it has been absolutely perfect in his tank - clear water and a happy Betta with bubble nests every day.
Over the past couple days, it seems to have dropped drastically and I can't figure out why. The water is cloudy-white and it smells terrible. I've done a 50% water change every day since I noticed this, but it still continues to become cloudy and smelly over a 24-hr period.
The only difference that's been made since the sour conditions have come on, is that I introduced a baby black mystery snail that I acquired for free from my pet store workplace.
I am going to take a water sample in to work and test it tomorrow, but I am worried about my Betta and don't want to see him belly up, so I am just wondering if any of you might know why the conditions have so suddenly become so poor. Is the snail the cause?
