I have a fugeray as my light source as well as the window that shines in. I dose flourish .5ml each week. And .5 carbon supplement, I don't have pressurized co2, and am scared to use diy in my shrimp tank because I have gassed my shrimp before. But it doesn't look like my tank needs any co2 haha. It's growing in well over the last month.
And yeah I feed them every once in a while at max 3 times a week. I alternate sinking Carno pellets, one of jakes veggie foods, spirulina wafers, and frozen stinging nettle.
Here is my tank, one month ago
And here it is now, only thing I added was blyxa, everything else has grown in
