Whats that noise???
Hi, I am 5 weeks into my first (properly set up) saltwater aquarium. It’s 55 gallons, I have 60 lb. of live rock and about 4 inches of live sand. I have about 15 blue legged hermits now and 20 turbo snails. I have evicted 2 stone crabs and a strange looking hairy legged hermit (returned to the LFS). At 3 1/2 weeks I added a peppermint shrimp, and a week later, after several daily water testing that came out negative for nitrate and ammonia, I added a diamond goby. Needless to say, I don’t see my two critters much. The shrimp seems to hide in the rock as far as I can tell, and I see raised areas (maybe burrows) in the sand in which I suspect the goby hangs out. I don’t remember when it started, but it seems like about the time I added the goby I heard popping or clicking noises from the aquarium in the middle of the night. I flew out of the bed to make sure nothing was trying to escape from the aquarium, and I couldn’t see a thing that could be making the noise. It doesn’t sound like it
