The last couple of days, my beta has been acting funny. His colour has gone dull and he is not as spunky as normal. This morning I noticed stuff on his fins! They look moldy and little pieces are missing?? Most of the time he just lies at the bottom and only comes up for air. I just change the water and filtters this morning to see if this will help.
Does anyone know what it could be??
