So I stated a 29gallon planted tank about four weeks ago. I got 10 shrimp (5 amanos and 5 RCS) a little over a week ago. One RCS has died. There are some green hair like algae on the glass and on a few plants. I'm just wondering if it's necessary to feed the shrimp also? I'm wanting them to eat the algae and not rely on the food that I give them.
