Symptoms and Treatment
How has your betta fish's appearance changed? He has a weird almost transparent offwhiteish thing on his head... It looks like this
, except only one. I also noticed, a few days ago, a lump on his side! It looks like this
How has your betta fish's behavior changed? It hasn't. He isn't lethargic. He's swimming around, pooping, eating, and flaring.
When did you start noticing the symptoms? The thing on his head I noticed a week ago. I noticed the bump a few days ago.
Have you started treating your fish? If so, how? For the thing on his head, I put him in a 1/2 gallon tank with aquarium salt. I changed the water every day and monitored his head. It seemed to disappear after about five days, so I put him back in his normal tank. Well, I realized that when I put him in the smaller tank, he lost color, so I couldn't see the thing on his head. In the small tank, his face turned grayish and his fins and body were greenish blue. In his normal tank, his face is black and his body is dark blue, his fins are red, dark blue, and slightly blueish green. I assume he likes his big tank better. After a day or two in his big tank, his colors came back and I noticed the stuff on his head again.
Does your fish have any history of being ill? No.
How old is your fish (approximately)? I don't know at all.
