So I have this CRS tank for about 9 months. When the light turned on this morning, i saw my shrimps were eating a dead shrimp. There was an empty shell next to them too. I have been noticing some shrimps are missing, so i guess this is not the first one. My question is, what went wrong? Do you think it molded and then got jumped by others? Or am I not feeding them enough? I always feed them twice a week, but since my shrimps have been breeding, so maybe i should feed a bit more... Also, can i just let them eat the dead shrimp or the dead body will course problems?
