I currently have a 38g hex heavily planted. 1 pleco 1 dwarf pleco of some sort, 4 leopard danios. 2white tipped tetras, 2 platies, and 2 corys.1 yoyo loach. Can I get a pair of german blue rams and if so would I have to add caves. And does anyone know where to get pearlite I can’t find it anywhere.
