This week I added 3 Ghost shrimp and 3 Amano shrimp, shrimps carry a small bioload and help with detritus, algae and debris. The algae eaters are doing very well but are leaving mounds of poop behind, I think they are eating the fungus off the manzanita? or brown algae that may not be visible to the eye.
Any way i hope the shrimps can help with cleaning cycle.. I'll be adding more in the future
