thanx, it should they are exploring now, i've noitce the africans don't do much after the lights go out so that is the time i can feed the knives with little compition
the only "problem" with the aro tank is the pleco constently moves all the sand from one side to the othe plants and all! makes a couple of mountains...the knives really looked cool in there. but with the cats bgks would definatly get eatten.
