So Im one week into cycling my first tank and it seems its taking a turn for the worst. I have a 10 gallon with a heater and penguin 150 filter and 3 zebra danios. The water tests are showing .5 ammonia and 0 nitrates and nitrites. Ive been doing 1-2 water changes a day, usually 20% but I did a 50% tonight because the fish looked like they were struggling. One of them is swimming in place near the top and the other two are swimming spastically. Also Ive been feeding as little as possible. Water changes dont seem to be lowering the ammonia levels. Any suggestions?
