I have a 10 gallon tank with just my one male, Blueberry and was wondering how often I should be changing the water and how you're supposed to do it?
I've been taking out like 50% of the water, just using a pitcher, once a week. Last week I took out all the water down to the gravel and then put all fresh water in. Should I be doing something different? Like do I need to take out all the gravel and plants and if so, how often?
