Hi there. I am pretty new with an aquarium. I thought I was doing OK (I’d say about a month and a half), but about a week and a half ago (9/10/24) - I noticed one of my guppies was sick with some spots on it (pictures attached). I wasn’t 100% sure if it was ich or not, most pictures I see have smaller whiter spots. Without any better theory, I proceeded with what I knew about treating for ich. I ordered ich-x, it shipped quickly but it’s not due to arrive until later today. So, I put 6 tbsp aquarium salt in and gradually increased heat to about 80.9 degrees. I also reduced amount of time light was on to let them chill. My understanding was that 1. Guppies could tolerate this heat & 2. Theoretically, this should be enough to kill ich.
I lost 1 guppy by the next morning (didn’t have spots) and after about 24 hours, my feeling was that they were struggling to breathe, so I added two air stones on either side of aquarium and slightly reduced heat. Intermittently, they did better (sometimes at top, sometimes seemed improved and swimming around). Around the same time this started, I had some plants I needed to get added before they died. Last night, I could tell I most likely was going to lose the guppy with spots by this morning - she was struggling with swimming at all. (I also had a shrimp I could tell was going to die, it was upside down, but until last night all the other fish/shrimp in the tank seemed to be unaffected - maybe it was unrelated).
Flash forward to today….guppy & shrimp was dead. Plants for sure are not doing well, a lot of leaves are transparent. I am really bothered by my whole situation. I did my best to diagnose & treat, but everything seems to have gone wrong and I thought I was doing a much better job of keeping fish this time around. I need to figure out how to figure out what’s wrong & how to fix these situations as they come up. I tried so many different things and there were so many different things that went wrong at different times, I feel like I failed. I’d really like to keep it going and enjoy this time around. 😔
So..additional details. I have 29 gallon tank. When this all started going wrong, I had 5 guppies, 3 CPD (celestial danios), 2 panda garras, 2 otocinclus, and about 8ish orange pumpkin shrimp. Normally temp was around 74-75. Water tests showed safe level of nitrates (I had added some plant fertilizer, normally nitrites were pretty close to non-existent. No problem with nitrites. I believe hardness was around 150ppm (maybe a little less, not sure on colors sometimes, lol.) No chlorine problem. Alkalinity some where between 120-180ppm. Normally pH was 7.4-7.8, was slightly elevated - around 8. I’ve attached some pictures of test results as well. (Strip reading is Tetra EasyStrips).
Advice for beginner is welcome.😁 Thanks!
