Goby keeps getting evicted
I have a 29g biocube. I have had my yellow watchman goby for just over a week. Three times now, he and his pistol shrimp buddy have set up a nice home at the base of a rock only to have the brittle star take it over and kick them out. I've had the brittle star for over a month and every few days he picks out a new rock to hang out under. He has three regular spots and those are the same spots that the goby/shrimp have used.
I can only assume this will continue to happen. Will this cause stress for the goby/shrimp in the long run, or will they be ok if they have to keep staking out a new home every few days? I'm hoping the goby/shrimp will discover some great little spots that the brittle star has never used, but they are a little more out in the open and I don't know if they will like that area or not.
Anyway, am I worried about them for nothing? Will they work it out?
