do males grow fast.i have my 9 inch male in a 75 for the next to months until i get my 150 set up.how many water changes would u recomend weekely.i usually do one every two weeks.
I'm pretty sure 1 per week will be fine. Just plan on that and play it by ear. I f the water starts looking cloudy or the fish act funny then you made need more. Also add an airstone.
