I'm worried that my tank may be overstocked and causing the aggressive behavior exhibited by my larger ghost shrimp. I have 20 shrimp and 1 male betta in a 10 gallon heavily planted tank ( 2 1/2 cups of Java moss, 1 marimo ball, 10 anubias, 7 water wisteria, some duckweed and frog bit ). They also have a cave that they never use. I've noticed that while the shrimp don't attack each other unless there is food, the larger ones (about 1-1.5") do like to pick on my betta when they see that he's eating. His tail is also looking a little frayed since they've been introduced about a week ago. I've heard that macro shrimp are often sold as ghosties, but I'm pretty certain they're not those species because mine have the orange spots on the tail and some red on the whiskers. Is this common just common behavior for larger ghost shrimp when over stocked? They only seem to go after my poor boy when he is eating even when they have food of their own!

Honestly if you talk to many shrimp experts they agree that ghost shrimp tend to be on the more aggressive side of shrimp species. Also ghost shrimp do commonly have red/orange spots. So they may be aggressive just because which may or may not approve with giving them more space.
