Hi ~ we have a 55 gallon tank that has been up and running with fish for almost a year now. We can not keep an Angel alive for longer than 2 days. We have tried from different pet stores with the same result. They are all babies, so I don't know if that is the issue or if we are just not doing something right. At first I thought it was the temperature, we purchased a tank heater and the water is at 79 degrees. The pet store says that our water is good everytime I take it in to be tested. Everyone else in the tank seems happy and healthy. We have a
bala shark, rainbow shark, 2 rosey barbs, 5 danios and an algae eater. The other fish don't seem to bother the angels, they just get in the tank, hide, then die. Can you please help?
