I set up a 55 gallon tank 2 weeeks ago, I have 5 mollies 7 neons 4 catfish.
I had the other fish in the tank for at least a week before I added the Angel fish, all the other fish seem to be thriving, darting around ect. But I have had the 2 Angel fish die within 3 days, and one of the 2 replacement fish is very lethargic after being in the tank for only 6 hours! The other fish are doing great.

NEW TANK SYNDROME!

FAST.....do a 25-50% water change....then read all the articles at the top of the page under "ARTICLES", on setting up a tank for beginners, and the Nitrogen Cycle.

Your tank wasn't cycled before you put fish in. The ammonia is now toxic, and the angles are very sensitive to it.....


OH YES, WELCOME TO FISHLORE!

I might also add that it would be an excellent idea to invest in test kit so that you can monitor the ammonia/nitrite/nitrate/ph levels of your water. I recommend the API freshwater master test kit. It's well worth the expense. You want to keep ammonia under 0.25ppm, nitrite under 1 ppm, and nitrate under 20ppm.

Your angels are your most sensitive fish, so that's probably why they're being affected first. In addition to the testing kit, I'd recommend Prime for treating the water and 25-40% water changes every 1-2 days.
