After noticing my guppy had a tear in his tail, I did a partial water change. I used the lee's ultimate gravel vacuum for the first time. After the water change I noticed the guppies hanging at the top looking funny. Did a water check and now have ammonia .25. So I did another water change about 20% and still have ammonia
I used water conditioner, I do not have anything to lock the ammonia. I have at least 5-6 fry in the tank along with 3 adult guppies and 5 cories, 2 danio. Not sure what to do now. Need help asap as I dont want any casualties.
