I don't know what else to put in the tank, but I am looking. It has to be something that will be able to co-exist with Shadow - the tank belongs to him. He is currently in a bow-front 72 gal and will likely be upgraded to a larger tank around Christmas - at least a larger tank is on my list to Santa

.
Also - with the speed and appetite of the Tetras - any other fish I introduce would have to be aggressive enough to get some food - it disappears fast with this bunch - if you snooze - you loose.
Just take a look at my signature for stocking info.
