I had a bad experience with an online vendor who had a really good reputation in the Cichlid community. I had four peacocks in my 75gal tank and ordered more from this vendor. During the time the ammonia suddenly rose to 1.0PPM so I tried for four days to contact this vendor to cancel my order of 4 more peacocks. I finally got an email stating he was sorry for the delay but he had cancelled the order. Luckily I was home two days later as the fish arrived on the doorstep anyway and I had no back up tank to put them in. Then I just measured the level and it is 2.0PPM. The fish are acting fine but I am so concerned of internal damage from the ammonia. I have done one 25% water change and added more Dr Tims on advice from my local aquarium store that sells cichlids. They assured me the ammonia will start to drop but how long can I keep the fish at this level. The vendor is very apologetic and I don't want to trash someone's reputation but I am upset.
