I've got a RCS in my sump that's all by itself and is much larger than the ones in my 6.6g. It's also clear from not having any light, so it isn't very nice looking. I'd get a picture, but I only see it once every month or two.I don't think a Dwarf Shrimp's size can be effected by the size of their environment like how the Goldfish are effected by the size of their environment.
I run into this as well. If I have about 50 in a 5g they dont get as big. I recommend about 10-12 adults. You will have 50 that need removed in no time.Their growth shouldn't be stunted if you have a small colony. As your population increases I have noticed that they stop growing to their full size. At that point you should remove some and the remaining few should reach full size again.
He does seem bigger, are they of the same age?After seeing this thread I decided that I had to catch the shrimp in my sump to directly compare it those in my 6.6 gallon tank. With much determination I finally caught the little bugger and it's been with the rest of the shrimp for a day now. When I first caught it, the shrimp only had 2 small red lines on it's sides, but the color is starting to appear now.
Here's the big one next to one of my normal "full grown" shrimp. The size difference seems much greater in person than the picture.

yes this is true but id also correlate the same experiences fish can get with stunting, such as when there are multiple competitors going for the "prize" getting their dna to reproduce that there is a unknown factor that can make them mature much faster than they would normally in order to get there dna into future offspring if he is mature even though smaller his % of having his dna into the ready and mature female go up.You can probably counteract some of the stunting by doing frequent WC in your small tank.
i didnt see anywhere that he said it was ammo/toxin build up, maybe i missed something? idk if the can or do produce a hormone that they can tell how much is in the water like some fish can thus wc = less % of that built up which can help prevent stunting that is a fact. idk if thats what u were thinking of or not but i would have to assume thats where u were going..To resurrect this thread:
I think my sakura shrimp are smaller in my 2.5 gallon than in my Ebi. So that's a 5.4 gallon difference. Also, what Shrimpnmoss said, I kinda disagree; I think that it's not an ammonia/toxin buildup they sense, but rather that they just sense that there are too many somehow... If that's possible.
