Hi, I have 10 crystal red shrimps in my tank. Information online seems to indicate that they scavenge for dirt and algae throughout the tank. I have an assortment of weitzmani tetras and red dwarf rasboras ( Thanks Dan and Ned all of them are doing fine, none of my tetras actually died as I had feared, they were just hiding). Question is, is the waste produced by the fish with a little uneaten fish food enough for the shrimp or should I buy algae pellets for the shrimp? My main concern is overfeeding. Any advice would be appreciated.
