I have tried all the things you mention and to no avail. They need large aquaria and lots of hiding places. Good clean soft water with an acid pH. I have tried 5.0 to 7.0??? The males dig and need a very soft substrate. soil or creek sand that is smooth. The females are always courting and the males are always nasty!!
