I have had my female betta Eleanor for 5 months now, and she has been very energetic until this past week. I've kept her in a small tank that I got at Petsmart and she has been happy in it, even though I know she needs more space. I got her a new tank that is 10 gallons and when I introduced her into it, she lost a lot of her personality. At first she would just sit at the top in the corners and be very lethargic. She wouldn't eat and started to form a white muccus on her body. I decided to put her back in her old bowl to try to help her, and I got her some anti-fungal medicine *Pimafix* to try to get rid of what I was told was fungus. She no longer has the white muccus, but she began to look like she had ich. I treated her again for ich this time using Ick away, which contains malachite green. It seems to be working on her ich, however she is still very lethargic and will not eat. I've noticed that much of her body is losing color (she is a beautiful royal blue) and she is now turning gray under her gills and around her bottom fin. She has also developed light horizontal stripes on her body, which I have seen in other posts means stress. I am very worried about my little girl, and I would greatly appreciate help on the matter. Should I put her in the large tank *with filter and heater* or keep her in her small tank for now to help her recover. I'm attaching images of her and of the new tank I am putting her in. I would really love some help so I can help her recover to her happy self. I normally fed her betta pellets and dried bloodworms, which she loved, but she won't move now when I put food into the bowl.
