Sand from cycled tank.
I just set up a 20 gallon long tank and I have standard gravel in it. I have a 55 gallon piranha tank thats been set up for over a year and the same SAND has been in it since I first got the fish. My question is...does sand hold the beneficial bacteria I need to start off my new tank?..or is it all in the filter and on the sides of the glass? Its not as fine as sand on the beach, but its like mushy sand when I scooped some out for a pic. If I had scooped some out and put about a foots worth, 1 inch deep of it in the 20 gallon long tank would I still need to either get some fish, shrimp or ammonia, or do you think the sand in there would really be enough?
Heres a pic of the sand just to give you an idea on what type it is.
