Hello, so I noticed a lump of my betta skittles side a few weeks ago but was told not to worry about it unless he stopped being active and happy. Well he was fine but last night I noticed him just sitting at the bottom of his tank, he won't move unless he needs to head to the surface for air, he reacts happy when he sees me but its like it takes all the energy out of him and he sinks quickly to the bottom
Of the tank. The lump is on his right side and only that one side, the scales appear raised but not in a severe amount. When he swims it is very strained like he uses all his energy to go forward and has to keep swimming in quick bursts. He sits at the bottom of his tank or on leaves all day long. Ill post again later if he eats anything tonight or not as yesterday I did not feed him. But the day before he was eating like a little pig with no problems.
I don't think it's a problem of over feeding as the lump is on his side and it doesn't appear to be an over feeding problem, but I'm no expert. If anyone has any ideas please let me know, I really like my betta fish and want to keep the little guy as happy and healthy as I can. I just changed his water but there's no changes yet.
Thanks in advance for any help,
