    I have a 20 gallon tank, been cycling for 8 weeks, started with ghost shrimp, then 2 weeks ago guppy feeder fry who are growing and healthy, last week 2 female Bettas completes my fishy family.
    I have been doing water changes with prime and feeding very little, when should I use the gravel vacuum? IMG_1072.JPG IMG_1110.JPG

    I clean my tank once a week and use the vac then. Do about 25% water change too.

    Welcome to FishLore!

    I hate to be the bearer of bad news but...there's a really good chance that one of your female betta's will kill the other. They really should be one to a tank.

    I use the gravel vac everytime I do a w/c because it cleans the left over food and gunk from the bottom. Once a week for w/c is a good schedule too. What kind of gravel vaccum do you have? There are a few methods to starting the suction (if it's not a mechanical/battery operated one) that do not involve putting your mouth to the hose. I'll elaborate if necessary.

    Well the tank is large enough for a sorority tank, but they would need to add another 4 female bettas ASAP. I think the minimum for a sorority is 6 females.

    But sorority tanks should really only be attempted by experienced fish keepers, since think in a sorority tank can turn ugly very quickly.

    I would just start doing w/c and gravel vac as soon as you can every week should be good.

    I gravel vacuum 1/2 my tank, every other week so the entire bottom gets vacuumed once monthly. But I have lots of plants and an UGF. I think the debris helps the plants.

    I only do 1/2 each time since some beneficial bacteria lives there. Your cycle is new so I would only do 1/2 at a time, weekly or every other week for a couple of months. Once you are sure your cycle is established, you can do the entire tank weekly.

    In my sand substrate tanks, I vacuum once a we ek but it only takes 1/2 a 5 gallon bucket to vacuum a 20 gallon cause the debris sits on the top.
