I received pistol shrimp and goby on Friday, shrimp went straight to work in building/ burrowing, goby was more timid and has been staying close to everything and only moving when something is close.. only millimeters though, today I found goby in cave that pistol shrimp has moved to (kicked out cleaner shrimp). Goby still scared of snails and very timid, I'll see how this works
(I will add that I think my hermit snipped off high fin off goby as it was there upon introduction to aquriam, goby hid next to my big hermit and had no fin once it came out onto sand bed)
Could you explain more about the sound/The click you here from your pistol shrimps, I have heard loud click... Sounds like thermostat turning off or on but louder, I assume this is a good sound to hear
