two days ago I though my beautiful betta, Hue, was having a heart attack or somethin. He was swimming very fast around the top of his tank on his side. Then sank to the bottom of the tank and stayed there for almost an hour. Now he swims around, eats but there are no bubbles on the surface and he just dosn't seem himself, he's still coming to me when I call but he's not as lively as usual. There dosen't seem to be any problems with fin rot or fungus but I'm still worried. any suggestions?
Worried hue's mum.
