I have had my betta, Turtle, for about 4-5 months now. He has a 1.5 gallon bowl, no filter. I always change his water 1-2 times a week with bottled water, same type every time.
He has been perfectly happy and healthy until about a week and a half ago he suddenly got pop-eye. He stopped eating altogether, barely swam around at all. He stopped reacting when i came into the room, and only went up for air every now and then. I immediately changed his water and went to the pet shop to get some treatment. They gave me Sera Omnipur, it contains malachite green. I treated him with this for the whole week, changing the water and putting in a fresh dose every 2 days. It actually helped, after a week, his eye started to look almost normal and he finally started eating and was quite active. He wasnt 100% yet but definitely much better. 2 days after his recovery started, he got sick again :( This time his colour seems to have faded around his head, he has 1 or 2 little white spots (i don't think it's ich - some sort of infection maybe?) and a sort of bump on his forehead. He has stopped eating and swimming again. Today his gills seem to be a little swollen, they don't close fully. No colour change in his gills as far as i can tell.
I've just changed his water again and put him in a yet another fresh bowl just in case. This time no medicine, I've already been using it for almost two weeks, worried it's too much.
Please help! I don't want to lose the little guy!
