I have a 8.75 gallon with one betta, a mystery snail, a nerite snail and 3 ghost shrimp (assuming they’re all still alive as they hide mostly). The ghost shrimp have only been in the tank less than a week. Before that they were in a smaller tank with the nerite. I never saw any aggression towards the nerite so I assumed it would be fine. However!! Just now I watch one of the shrimp come out of their cave and start harassing my great big mystery snail! I used a chopstick to shoo her away and she went back inside. The mystery was startled but didn’t completely close his shell like he does if the betta is bugging him. Is this normal behavior or do I have an aggressive shrimp who needs to be removed from the tank? I know for a fact that the mystery and nerite occasionally go into the cave where the shrimp hide and it’s making me paranoid they’ll come back out sans eyes or antennae. Pics for good measure.
