Will they eat each other?

[207Meg]

The tank is a 15 gallon cube. It's been running a year. Corals are doing great, thriving, growing, spreading. Only soft corals, mushrooms, cloves, toadstools, xenia. The only inhabitants are three astrea snails, 1 nassarius snail, 2 pom pom crabs, and one blue line goby. I just ordered some beautiful rock flower anemones. I plan on getting some sexy shrimp after the rfa have settled. I want to get a unique fish for the tank, and was thinking of a coral croucher goby. Would this goby eat all the crustaceans?

Crouchers are not a goby, but a scorpionfish (same family as lionfish).
Like any scorp, any invert small enough to fit in its mouth is going to be food.

There's some risk of it eating the sexies, I doubt it would eat the snails, the pom poms (if they aren't babies) or the blue line.

Being a dwarf, it should not eat any and often hangs out within corals and only real caution is being with other tankmates as their dorsal is venomous towards tankmates.
Thet are easy to feed eating brine shrimp, small plankton, Chopped Krill and LRS nano frenzy as well as Mysis shrimp
