I keep my GBRs in a little harem (1M/3F), though the male seems to have paired up with a favorite female. Twice now I've found them tending eggs, usually guarding them well before eating them a day or two later. If they do get it right, I'm all for that. The question is, when my rams make little dome-nests in the sand, is that indicative of getting ready to spawn? They've made about four or five of these in the last few weeks, but I haven't seen any eggs.
