My catfish tank has a baby Arowana along with Cory cats, Clown Loaches and a Synodontis Catfish. While the Aro will be moved out when it's a bit larger, the catfish will remain.
I have the lighting schedule setup so there is enough light for the plants and then it switches to the blue LEDs. The catfish don't seem bothered by this at all and it allows me to see them swimming around at night. Awesome.
Oh, also, if anybody knows plants, if I plant those shoots at the top of my Swords, will that make another plant?
