I just got a free 29gallon today. So I leak checked it, then cleaned it out. Then I painted the back blue. Next I tore down the 20long, saved 10 gallons of water from it in buckets. Transferred half of my substrate to the 29, and using the same filter. No I have a 3.5" sand bed, and I noticed eggs in the hollowed out driftwood. So, will the tank cycle again and will the eggs make the transition?
