hi, my best friend has about 15 gallon tank thats about 2 - 3 years old.The problem is that her fish keep dying. She use to have 4 danios but 2 died.So she got 3 danios more but then one by one they died.She has pleco named spike and she doesnt want it to die bacuase she had it 4 a long time and raised it when it was just a baby. Also in her tank we notice that spike isnt eating alot. Anyway I have another question is it bad to move around gravel in your tank while fish is still in there? Becuase my friend thinks that its not bad to do that. Can anyone help us please?
