Our spotted gar isn`t big enough to go in the big 20ft tank, he`s in a 9ft x 3.6ft x 2ft tank and is about 18" long. He is a very peaceful fish along with the 3 others we have, eats well, and gets along well with a range of fish from the longibarbis to the lungfish.

Oh, and the big 20ft tank is in the fishroom, all the others are in our lounge!!
