ghost shrimp

i think most shrimps eat plants if there is no other source like algae or leftover food.
especiallly amanos, they eat almost anything, cockroach, crickets, dead fish, plants, and of course the algae.
unlike otos they dont really starve themselves. in my experience, ghost shrimps are more easier to take care of than otos
 
ghost shrimp are really sensitive to ammonia so make sure its the last thing you add to your tank.
