I am completely new to this site and new to owning Betta fish so forgive me if something similar has been posted. I am bit worried at the moment about my Betta. I did read up a little before purchasing one of the lovely little fish, but am still learning proper care.
I bought Zeus on Tuesday at Petco. He is in 2.5 gallon tank, no filter... but he does have a heater and thermometer (water is around 80 degrees F currently). I also bought a air stone/bubble stone. I have both live and silk plants and a light overhead. The water has been conditioned. I feed him flake food once a day (in the morning). He has a healthy appetite so far.
I don't know if I am just being paranoid, or if something is wrong. Overall, he has seems pretty happy and energetic. If I walk over to his tank, he will swim over to greet me. But tonight I've noticed that he will just sit/rest at the bottom of his tank for certain amounts of time before swimming around for a bit, or going to the top to blow bubbles. Is this normal? Is he just lounging? I don't notice any discoloration. His back fin is bit tattered, but it was that way when I brought him home. Some of the fins are clear-ish white on the edges, but it looks more like new fin growth than finrot. I could be wrong.
