I am actually not using any. I added stress coat to help him heal the missing part of his tail, but I understand this is not really a medication, rather a soothing additive, kind of like us having a nice cup of tea. But if you guys think I should not add it then I wont.
Also; on the timeline:
He was lethargic for 2 days before he got ich, there were no changes to his tank, but he was with me for only 2 weeks then, so that in-itself was a change.
During ich treatment I followed instructions for 10 days using warmer water, ich medication and AQ salt. I removed him from his tank and put him in hospital setting, no gravel, no toys, no shelter, no caves, just his heater in the tank. he got happy the day after treatment started and had no problem eating or anything. In fact the ich cleared in three days but I pet the treatment duration for the full 10 days as instructed.
It took 4 days to taper off meds and adjust water. he was happy the whole time.
On day 15 he was put in the new tank, same size, water temperature Etc. He was fine and happy for a couple of days even though the water was cloudy. I was told before this was a bacteria bloom and the only way to get rid of it was to filter the water. I ignored that as I have been so strongly advised against a filter before.
On day 3 in the new tank he got lethargic and someone suggested to do a water test, which I did not have the kit for. I got the kit and found the water high PH and ammonia at .50. this was not acceptable and I assumed it was the reason for his sadness. Water change again, this was when I discovered it was my tap water that was the culprit. ( made another post for this and I am still learning about it, not doing anything, just learning). I was advised to change my water conditioner to prime, which I did right away.
So i got a high PH test and found the water to be 8.8 ph. i also tested my tap water and found it also tests high. I know you can adjust it by driftwood and peat moss but I can't find any locally, so I have no choice but to use PH down until I do.
So I changed the water, and added the ph down to lower the ph to 7.6 - should I be keeping it at 8.8?
The second day he did not eat (late night when I got home from work) I noticed the spot on his tail, which was white and fuzzy and significantly larger than the ich spots. I went to the forum and searched for what it could be and the closest thing I found was fungus.
Again, changed the water (100% each day). the treatment for fungus is AQ salt, but since he just got off a 10 day treatment I was not sure if it was a good idea to start again so soon which is when I asked here, and as I thought it was right to not start.
I added the filter at a low flow ad advice of someone who reminded me that fungius will grow in still water, and the water may not be even all over as I have seen myself how it develops into layers. I am sure he likes the filter, he will sit right on top of it. It does not create a current, it does not break the surface, it barely moves the water, just enough to create a small circulation.
The water was crystal clear after I put the filter in and is still that way now.
I don't think it is harming him and as someone said before, I do not want to take stuff out and in all the time, he doesn't like change.
The next day I found the spot had dissipated and a hole in his fin appeared instead. There was no blackness or redness around it. I added stress coat to help him heal. (I was told this was not a medication, it was just to suthe his skin and help his slime coat regenerate in the spot it was torn).
Guppy felt better, he started to swim around more and eating, but his behavior was weird.
By the end of the day his tail basically ended where the hole had been which I can assume is only because of the damaged tissue and I am hoping it will grow back.
today, I did another water change. only about 80% as I did not want to stress him more.
He ate today, but is still acting weird.
I am very confused by all the advice I am getting. Don't use PH down but anything over 8 will kill your fish - I have 8.8... what am I supposed to do?
Should I stop using the PH down?
Alive and hard of seeing is better than dead, though I would prefer if he could see well. I am very concearned and very confused but I am not actually doing anything except water changes. I was told to move him to the hospital tank, i did not do that because I did not want him to get stressed getting used to a new environment again.
Someone also told me to take out all plants, but I have no live plants in the tank.
Even though I am panicked, and I do worry and ask many questions, I don't actually do as many things as I was told to because the poor fish would just feel like he is in a roller-coaster.
Now you are telling me I am doing too much.
I am not sure what to do at all now. I feel like I should stop trying to adjust his water parameters, but then I know, as I have been repeatedly told that he will die. So am I supposed just let it be and let fate take it's course?
Should I bring his PH back up or should I keep treating new water to keep it the same as it is now?
I feel like I am between a rock and hard place. It is very sad because Guppy is the one paying the price.
