basically my tank substrate is sand (around 2" deep)
and ive read that if left alone there is the possibility of anaerobic spots which when moved releases toxic chems in to the water.
i was wondering was there any fish that will burrow and disturb all the sand so that this doesn't happen,
thanks in advance
