I have had fish for 20 years and livebearers are the absolute hardest fish for me to keep and I don't know why. I have tried relentlessly over the years because they are some of my favorite type fish, especially the guppy but never have much success for very long. I have a 55 gallon community tank with 3 black neons, 10 neon tetras, 1 red tailed shark, 2 plecos, 1 cory cat and 7 or 8 guppies (at the moment). My guppies are never quite right and I'm always having to buy new ones. I buy from breeders so they are very healthy fish when I get them. Over and over they eventually become sluggish, clamped fins and develop fin rot. I have experienced the same problems if I have tried mollies or platies as well. I continue to have lots of success with any other type of fish. I haven't lost one neon tetra since I bought them months ago and in the past those had always been difficult fish for me to keep. Some of my fish in this tank I've had for years and they've always been so healthy. Why do I have such poor luck with guppies? I'm determined to make this work but I've spent so much money over the years only to keep loosing them.
Here are my tank stats:
We have well water and I have had this tank set up for years.
