My betta fish has this white dot on his head as well as some tiny ones on his body that can only be seen up close. I first noticed it when I was putting him into my tank when I got home from the pet shop. At first I thought the dot on the head was just a scale that had lost its colour but now...

Alright. So this is Romeo. He already has SBD and we have been fasting him for a few days and 2 nights ago we gave him a pea. He somewhat seems to be doing better. He is still having problems floating down to the ground and swimming in general.. but that is not what we are worried about now...
