The last couple days we noticed one of our Cory's laying on the bottom of the tank but not flat on his belly. One side slightly higher than the other. Has a couple small red dots below eyes on each side. Acting much more lethargic than the other Cory is.
LFS says it sounds like high ammonia. Wants me to replace filter and do a water change.
I did a 50% water change on Saturday. I tested the water with the API Master kit before the change and ammonia and nitrites were 0 and nitrates were 5. I am at work so I can't test until tonight. LFS says that ammonia is much higher at the bottom of the tank so it affects bottom feeders first.
So when I test tonight, I am going to use the syringe that I have been using for the last 3 months to pull the water samples and pull the sample right from the bottom of the tank.
In the mean time, I am having my wife pour 3ml of prime into the water, just in case the ammonia is high.
Anything else I should be looking at to figure out what's wrong with him?
