I have a small 6 gallon long with 8 pygmy cories and 10 amano shrimps.

The shrimps were added yesterday and they've been aggressively stealing every algae/cory wafer I put in the tank. They are simply faster than the cories.

My idea for a solution is to feed the tank freeze dried black worms. I can't do the popular frozen bloodworms due to covid. I also can't do the popular freeze-dried hikari bloodworms because they never sink to the bottom.

So would freeze dried black worms work? I figure I'll break off a tiny piece of the block and stick it to the bottom of the tank.
