Hi all, so recently Iāve noticed my beta fish has been moving around less and less, and overall seemed sluggish and his fins were starting to lose their vibrancy and get smaller. Today I got home and found him on the floor of the aquarium just lying there and occasionally flopping around. He is about 3 or 4 so Iām wondering if itās just old age, because it has been fairly gradual, but is there anything I can do to help, or am I doing something wrong? Thank you! And please keep in mind, this is my first fish, and Iāve done my best but Iām far from great
