Second fish found dead
Hello. I am working on a 16g FW
tank that has been up for 9 days and is already starting to cycle. Last Friday, an unauthorized fish (Betta) was put in the tank and was found dead Saturday morning. I removed it and watched my other fish. This morning, I found white spots on the fins of 3 fish. This afternoon, I re-tested and my ammonia was up to .50ppm (up from .25ppm yesterday). I just completed about a 30-35% water change, my ammonia still looks like it's .50 (I may not have waited long enough after water change, will try again in a couple hours).
DURING the water change, I found one Zebra danio floating. It had a noticeable white/gray ulcerous patch on the underside of the gills. Is this the result of ich? Ammonia? Or do I have something else going on. I have removed all the silk plants, because I am getting ready to treat for ich and don't want this stuff to stain them (which of course means I have to boil them, don't I?).
