I noticed last night while watching my new purple firefish explore his new home that there were bubbles every now and then coming from my DSB. I think I remember someone saying before that this a good sign. Is it caused by critters moving around and causing other biological processes down there? I also notice some bristleworms for the first time this week. There was one that was about 2 1/2 inches long which made me very happy.
