Hello, I came back from the LFS today and saw a dead shrimp in my Betta aquarium. The other shrimp were barely moving, and one of them that was sitting on a leaf earlier today was still there, right at the same spot. I got a ruler and started slowly moving it in front of the shrimp, and the shrimp just slowly backed away. Usually when something is coming towards them, when they touch it they immediately jump out of the way. There was another one in the micro sword, and one on the stem plants, but I figured out they were alive. So I did a head count of the shrimp(counting the dead one) and I came up with 4. I have 5 shrimp. I checked under the rock cave thing and behind ornaments, but I couldn't find the 5th shrimp. Also, they haven't been swimming around like usual lately. Do you think the betta ate the missing one, and that they're trying to hide because the betta is hurting them when I'm not looking? I think it's unlikely that he ate the shrimp, because he isn't abnormally fat, and if he ate one, he probably would've eaten the dead one too, right? And, lastly, what do you think is the best thing I should do? Thanks.
