extra info from my experience, if you find any shrimp tht is very inactive, lying down like they are dead but still slightly move..try to feed the tank using fish food like micro pallet preferably food tht contains protein. make sure some of the food falls near them. they will try to eat the food and actually recover. happened to me few times and the shrimp is still alive and kicking for a few months. i surmised tht this particular shrimp might have starved or lose energy due to molting. however this method isnt 100%. just sharing if other people have this problems. and do not isolate them to other container as tht can cause unnecessary stress
I have a small colony of 25 cherry shrimps, 7 amano shrimp and 2 bamboo shrimps. In a 75 gallon planted community aquarium with fish and 8 dwarf orange crayfish. Although the shrimp were going after the food the day I got them. They haven't been touching any of the leftover hikari shrimp food I have been giving to the crayfish. Instead, they are sticking to my plants, and I rarely see any of my cherry shrimp or amanos looking for food on the substrate. Leaving me only to have to feed my bamboo shrimp and crayfish daily.
I feed my shrimp every other day. I feed them Shrimp King Complete. They recomend I stick for every 20 shrimp, but I think that’s too much food. I have 100 shrimp approximately and even 3 sticks last more than 12 hours. I’m cutting down and experimenting with feeding less
They are always grazing on algae and biofilm in the tank. So if you have a good amount of those things, they may not need a lot of supplementation. Not sure how often you feed but sometimes twice a week is good enough
