Hi there!
Dont worry about cichlids digging, if u do u'll be worrying for a LONG time! Its perfectly normal behaviour for these guys. My African tank is littered with pits, caves and furniture thats been moved around, dug up or in one case buried under. They dig to build nests, search for food and most common of all because they like to cause aquascapers problems!
Its hard to pin a cichlid down by its look/body shape, i bought ten various alunacaras and i cant tell em apart!
Look forward to seeing ur pics any way and dont worry about ur fishy pal, perhaps u should callhim Dug?
