This tank is close to 3 months. Yeah that CRS is caught out in the open, usually he hide behind or under that sponge. I had 2 berried but all the eggs seem to disappear, I guess 1st time mom.
PH is 5.5 from MVP Turface soil. Some said they will go back to neutral PH but it has been a long time and still at 5.5. I don't know if 5.5 is the cause for shyness.
P.S. I do believe light is the cause of shyness =). In the morning whenever I turn on the light about 8 AM they start running toward the driftwood and disappear for the whole day until light is off.
