I came back from a week long vacation to a lethargic betta of 2 weeks in a 10 gallon. He was sick with swim bladder disease when I got him from the store but was very active in the aquarium. I had to fast him prior to vacation time because of the illness and fed him 3 garlic soaked pellets before I left to help the digestive tract. Anyway, the lil guy isn't doing so hot right now and is lying on the floor with his gills moving quite a bit. He can burst some energy to swim up but quickly goes back to the bottom. I plugged in my bubbler just in case it was low-oxygen, but I had two sponge filters constantly running with my baffled HOB. I cycled my tank way before and have 0/0/10 readings. I did a 50% water change anyway and saw no improvement in the betta's condition. What more can I do to help it? Is it just starving? I tried to feed him but he is not interested at all. Thanks for your time.
