Florida gulf live rock goes in the tank. Never added more rock, and the tanks been up since September/ October.
10 gallon tank, "nano sized" rock.
I originally thought my pistol shrimp dragged a snail underneath some rock work, but how could a snail be stuck/ make loud noises for a week straight without dieing or being eaten by my shrimp? I checked that possibility off of my metaphorical list. Next, I assumed tht my pistol was rearranging rubble to reinforce walls, but it is very loud and I was able to check this off of the list also when I heard the noise at the same time my shrimp was out In the open. I thought for a split second that my pump was hitting glass, but cancelled that out when I unplugged everything and still heard it.
On top of the noises, every so often I see a large amount of bubbles come up from underneath/ behind my rocks. ( my rocks do not move during the noise or the bubble action) I have tapped, knocked, damn-straight shook my tank and during all of this, the sound continued. It is mostly at night, but is heard sometimes in te daylight. Somebody help me out, a mantis would leave a mess, and I can't see not witnessing anything like this in the past 5 months. (all though idid find that thing in the thread "what in gods good name is this" just a few days ago)Any ideas?
