17. When was the last time you bought a fish and how did they behave while in the pet store tank? Saturday 26th May, they seemed fine, I couldn't see any sick looking fish in the tank. I probably didn't inspect them as well as I should have though.
Hello, my tank just finished cycling last week and I added 6 Neon Tetras on Monday 19th and I tested the water and there was still no ammonia or nitrite so I added 5 more on Saturday 26th (I asked for 4 but he gave me 5 by accident). On the Sunday I noticed that one of the fish was missing the tip of his tail and it looked a bit white, thinking it was fin rot I went and bought Interpet's fungus and fin rot treatment and added it to the tank. It looked much better the next day so I'm not sure if it actually was fin rot, it seemed to go away so quickly. Now today, I can see 3 little white spots on the same fish and it's breathing rapidly, but not gasping at the surface. The white spots are on the top of his head, one the the gill and one on his side. Another fish's red colour is faded and is also breathing quickly and another one's neon blue stripe stops and starts. Where the blue stripe stops, there is a slight lump, this fish has been this way since I got it, is it anything to worry about? Here's some pics, I couldn't get one of the fish with white spots.
Other than the interrupted blue stripe, this fish is acting normally.
The fish on the right has faded red colour and has rapid breathing but the blue/green stripe is still bright.
So now I'm not sure what to do, I have a carbon pad for my filter that I'm not using, I could use that to get rid of the fin rot medication, then treat for white spot? All of my fish are still eating well and apart from the three fish mentioned above all other fish seem healthy.
I bought Neon Tetras as my LFS didn't have any Cardinals for sale and the guy there told me that Neons are more hardy anyway...
It's probably something I've done wrong and I'm sorry if it is, please tell me how I can make them better.
