Hello, I am new here so please forgive my ignorance. My husband has an African dwarf frog that he received 5 years ago for his birthday. To be completely honest, we really didn't fuss over him much over the last 5 years as we are not really fish people and the gift was a completely unexpected surprise. He was in one of those self-sustaining 5x5 plastic tanks when we got him and we just kinda let that roll. About a year ago I felt bad and ordered him one that was slightly larger and did a tank change with no issues. About a week ago, I figured he was sticking around so I went to petsmart and got a 2.5 gallon tank that had a filter (his tank would get pretty dirty before we would get around to doing a water change), some plants, and a heater as he had just been in colder/room temp water for the last 5 years. Again, we really didn't know what we were doing and only went with what we were told when he was given the frog for his birthday. When I swapped him into the new tank he hung out by the filter a lot and I just chalked it up to him liking the vibration. About a day into it, the water started getting a little cloudy which I thought was weird because I used bottled spring water in the tank and he now had a filter. About 3 days into it he started to swell which then caused much concern. I went back to the pet store because I remember them telling me when I was purchasing the tank that they do free water testing. I was informed that everything was good but the ammonia was really high and was given some bacteria drops to put into the tank. Two days after that (yesterday) he still really swollen and now I am really concerned. So I took more water back to the store and they said the same thing about the ammonia, was told the same info which upset me because I already did everything they told me. I asked how quickly this should change and his response was "pretty quickly" but then I asked him to please define pretty quickly and he said "a couple of weeks". I don't think my guy has a couple weeks. Something told me to keep his old tank so yesterday I put him back in his old tank (tested the water and all is normal) but he still really swollen. He's active so I don't think its dropsy but I have seen a few threads where people have talked about aspirating the fluid out of their frog or beta before and didn't know if that should be something that I look into to help this little guy out. I get that my ignorance is the reason that he's in this situation but from what I have read, having him this swollen is painful and hard on his organs. When we got him, he was just an annoying birthday gift that we didn't ask for but now he's become a part of our family so we want to help him as much as we can. So I guess my question is, do you think the swelling will go down now that he's in an appropriate environment, is there anything that I can do about ammonia poisoning or should I look into possibly aspirating the fluid to have him go back to his happy normal life? (the photo I have attached was his last day in the new tank before I moved him. Looks like the swelling has gone down a TINY bit but he's still really big) This was him 3 days after the new tank.
