Urgent: Pleco Not Eating For Over A Month!

Hello,

We moved to our first home on 8/24 and transferred my tanks on 8/27. My 29 gallon high ended up having a leak before the move so I upgraded to a 75g. We were doing some renovations and repainting, so the fish from the 29 gallon (including my pleco) were kept in a large rubber tub with heater, bubblers, , and frequent water changes until I could set up the new large tank. I was able to get all the fish in the 75 gallon around 9/28.

The pleco has not really been eating since the move to the new place. All of his stress marks seem to be better than before but he still has them. No other signs or symptoms of disease.

I've tried feeding, cucumber (his favorite), brussel sprouts, bottom feeder wafers, algae wafers, and bug bites for plecos. I even was able to drop food right in front of his face today and he didn't even care. A few minutes later he just swam away like nothing was there. I'm assuming he's living off of the driftwood at this point. Food is untouched and rotting in the tank before I take it out where as before he'd swim over instantly and sit eating for hours. All of it would be gone by morning.

All 4 of my fish in this tank have died in the past week. I have done water changes of 50% but the last one died today. Now only my pleco is left! They were all eating normally. No signs of disease. No torn fins or red gills. Nothing.
I use and for water changes.

Water parameters:

Temp 77°F (it did get to 80°F earlier this week. I added more air in the bubblers and opened the glass tops)
7.6
9°
4°

0
Nitrite 0
Nitrate 20

I do have nitrate in my tap water. The online water report says 2ppm.

I need help ASAP! I don't want to lose my pleco ;-;

 

When we first got our BN pleco he wouldn't eat either. Then we read that they really like garlic. We took zucchinI slices and finely chopped garlic and let it soak together overnight in a small cup of tank water. Then we placed it in the tank and he went nuts for it. Apparently the garlic can help a little with parasites too. I know Seachem sells Garlic Gaurd, if you want to try that route instead. Good luck. I hope he eats for you.

I'll try anything at this point. I've had him for 2 years and he's always eaten.

grrrr worrying. Doesn't look thin in the fit (as far I can see)

This was the last photo I was able to get of him on the tank wall. I believe this was about a week ago. Def not thin. There's nothing in the tank but him.

 

Final Update:
I did a 50% pwc on two days ago and he was rather active and actually out and about. I checked on him yesterday and saw him on the substrate and thought I saw a little white patch on his head. I couldn't really tell, so I figured I'd check the next day. So tonight I went to check on him and found him dead covered in the white stuff. I can't believe he started degrading that quick... the tank smelt horrible. My bf netted him out and we nicely put him in the trash since I didn't want to flush him. I would have buried him, but we had a snow storm a day ago and we're covered in a foot of snow.
RIP pleco

 

I am so sorry for your pleco. RIP
