I have three guppies, whom are my first guppies ever, that I would guess to be two years old. At the very minimum, one and a half years old. I have a girl whom I believe is exhibiting signs of old age.
During the day, she is as active as ever, swimming about the tank and socializing with the other girls. But for the last three days a about an hour before lights go off, she has been resting on the bottom of the tank in the same general area. Occasionally, she swims off the bottom, but she isn't as energetic. I get worried about her the night before, but my morning, she seems back to normal.
Anyone here know what typical behavior or symptoms of an old guppy is? She has been through many pregnancies and births under my care, and I'd hate to lose her.
Thanks for any help!
