Hi, I have a question about my guppy. She was purchased a few months ago and was fine. I put her in my 20 gallon high cycled tank with 7 other glofish (tetras). In the recent week or two I've noticed she's not active, laying on the bottom of the tank. She perks up a tiny bit for food but she didn't and still won't come to the surface to get it. Her food was tetra food, and she had some diotoms to munch on. (I know the diotoms aren't a nutritional food, but it was just extra). Was feeding the tank 6 days a week with Sunday's off. About 40-50% water changes every 10 days-two weeks. I was bad one month and forgot to clean so I had to do a large water change. Now I do about 25-30 once a week. Anyways I took her out of the main tank and set her up in a mini tank w a heater and filter. I put some parts from my main tanks filter in to get it cycled plus seachem's prime. She seemed to be perking up and much more lively after a few days, I also gave her hikari micro pellets. So after a bit I decided she could rejoin her old tank, but things got bad again. So finally after doing water changes and trying to or hikari food for her, I put her back in the mini tank. I ripped off a piece of mesh/foam from one filter into new one as well as some plastic part which I think held a sponge in it once, and put it in the small tank and let the filter run. I had to shut it off though because it seems to be very strong and makes her kinda shakey. She had a heater and I try to keep t at 76-80*. Around the same temp she had in her 20 gallon tank (78+/-2)Which I know fluctuates but I don't have any other heater besides this one which isn't preset. I give her only the micro pellets and at times after she eats she seems to be doing much better and I think I caught her swimming up in the tank and flailing around a bit. However I'm not sure what to do going forward. Here are a few pics of Ivanka when she's down at the bottom. Can anyone give suggestions? Also I've noticed one very thin and short clear hair looking thing coming out of her but her poop has been food color. I do have some old prazi I could throw in there?
