Betta/ shrimp planted tank
First post and new to the fish/shrimp world. I have a 7 1/2 gallon tank with 7 RCS, 2 Blue Velvets, and one yellow. Also I have my betta fish with them. I have hair grass and a smaller plant that they seem to like. How do I go about feeding the shrimp so the betta doesn’t overeat? Is it okay if I turn the light off for the shrimp? I usually do at night for Jeff(Betta). How will the shrimp breed and how can I ensure they will?
