Aquarium Advice FINatic
I have a 30 gallon freshwater tank that I have been running for more then 2 months now. I've only had 2 tetras in it from the beginning until the tank "settled". Well everything was great for these two months. I checked it for ammonia and there was a slight trace of it, so I did a 40% water change and the ammonia went away. I decided to purchase more fish about a week ago. I had a gift certificate for petco.com and noticed the started shipping live stock. I decided to give them a try. I ordered 2 kissing gouramis, 1 redtail shark, 4 more serpea tetras, 2 rainbow's, and 3 green tiger barbs. Well the first day I introduced them to the 30 gal. tank everything seemed fine. They were swimming around exploring and right away I fed them a little bit and they attacked the food. They just seemed very happy in their new environment. The next morning I found 1 of the rainbows dead with no signs of any kind of injury or disease. Right away I tested the water for ammonia and found that I had an ammonia spike. Keep in mind that prior to adding new fish there was no ammonia. Well right away I did a 35% water change and added some ammolock. The rest of the fish seemed healthy, swimming around exploring, no signs of stress. The next morning they were all good and healthy looking. Later that day when I got home from work I noticed the second rainbow stock to the filter intake and noticed it had some fluffy cloud looking mucus around its entire rear(bacterial infection?) I transferred it to a 5 gal bucket I had and it didn't make it, died few hours later. Again I tested the water and to my surprise the ammonia level was even higher then it was before I did the 35% water change. I didn't do a water change right away and waited until the next morning. The next morning all the fish were swimming looking good and eating like any healthy fish. Well I did another water change of 35-40%. Another day passed and the fish were looking good. I did a test for ammonia again and just like that it was gone. I thought everything should be cool from now on. Once again all the fish looked healthy swimming around exploring still. Another day passes and I started to notice one of the gouramis wasn't swimming as much as the other kissing gourami and its tail was split. Again, I did the ammonia test and there was no ammonia this time, so I didnt think of it much. Well today I woke up and dammit, that kissing gourami is no longer breathing. Right away i did another ammonia test, and still no ammonia traces. I decided to do an pH test and it came out to about 7.6-7.7...which I figured is a result of all those water changes. Does anyone have any idea what is causing all these deaths? pH too high? some silent disease? Right now all the fish are looking good. Sorry for the long post, I just don't know what to do any more.
