Fire shrimp - Lysmata debellius

[i cant think]

I have a Red Sea max nano with a Pom Pom crab, a conch and abour 6 other snails. I have a huge love for shrimp and I’ve always had a fire shrimp in Atleast one of my tanks. Now I would put him in my 4’ tank but I have 2 L. amboinensis and a S. scutellatus already residing in there.
My question is, how bad is the fireshrimp’s aggression towards small fish (Discordipinna griessingeri), and Crabs (not hermits)?

In my experience fire shrimp never showed any type of aggression towards any of my fish.

Mine never showed aggression to my fish but it wasn’t exactly a totally peaceful tank like I have now.

Never seen fire shrimp hassle any fish or crabs. They can go after other shrimp tho

Yeah, that’s not my issue anymore thanks to a mystery that seems to have been solved.
