The tank was a large pillar with a domed shaped container at its top. At the top of the dome was a number of shapes crafted onto its surface that resembled a large number of Goa'uld symbiotes. The opening at the top of the tank was capable of being removed which allowed a person to see the symbiotes inside which swam in a liquid substance.
Daniel Jackson snuck onboard the Goa'uld space station in the Hasara system and found the symbiote tank waiting by Transportation rings. At the High Council of System Lords meeting that discussed Anubis's entry into the ranks of the System Lords, a symbiote tank was ringed into the council room.
