I've a group of 3 wide bar Sd's about 5-6inchs in a 6' 150 running a fx5. while they will schoal they seem to hide constantly. Except for a lisomadoras Oncicus their the only inhabitants. Do I need more to bring them out? or is it something else going on? was a bare bottom recently added sand couple of large pieces of wood and some big clay pipe pieces for cover. thanks
