After not having a tank for over 10 years, I finally decided to set up a new tank. I got a 55 gallon. The guy at the local “expert” aquarium store told me that I could use this tank starter stuff to immediately cycle my tank. I was dumb and I believed him. My tank is now cycled after 2 weeks but my poor fish are showing signs of a number of diseases. I’m hoping that someone can tell me what the most common ailments are in fish that were exposed to high ammonia and high nitrites so that I can narrow it down and figure out what medication to try first. I did daily water changes as soon as I saw the ammonia spike until the end of the cycle (which I think is the only reason why they are still alive). Im going to try to post pictures but here is what I am seeing: The big orange platy has clamped fins and developed a area of what looked like bleached out scales on her back. Now it’s starting to look a little more like a raised whitish patch but still pretty flat. The guppies fins are looking ragged and I’m seeing spots on the fins (it doesn’t look like ick bc it’s only on the fins and it’s only visible when I look at the fins from the side with the light shining through). One guppy has a whitish patch on his back that just today almost certainly looks like fungus. Ugh. Hoping for help. I ordered a bunch of stuff from amazon but it’s not coming until Friday so I’m hoping to fHire out what this is so that I can go buy a medication to start ASAP.
