Hi, I am completely new to fish and FishLore, but I am very serious about it now and I need some advice before my little fish suffer. I have a 29 gallon tank that has been set up for 3 weeks. At 2 weeks, I put in 3 angels and 1 week later I put in 2 pictus cats and 2 snails along with some bio spira. My ammonia is too high and there is no sign of nitrites. This was 6 days ago, so should I do a water change, add some more bio spira? Help please!!!
