Sulawesi Cardinal Journal
I'm setting up a tank for some sulawesi cardunals in the future.
I'm going to house them in a 20gallon long running dual sponge filters right now theres only two I'll add some more or air stones later on.
when i first set it up it was kinda plain I didn't feel as if there was enough surface space.
I'm using a very fine layer of crushed coral with 20/40 grit black beauty blasting sand
