Just to let you know, as I was fairly confident mine would spawn on same substrate again (as it seemed they really liked the spot they had been laying them in), they decided to switch it up on me....this time on the back of the tank wall....This is the first time since the Halloween spawn, but they have been relocated since then and I didn't expect them to go their normal 3 weeks as they do when they are not constantly being moved....It was about 6 weeks since the move,...this is fairly consistent with the timing of their previous move up from the coast.....Not sure what this means to you, except maybe...don't trust them (lol), ....no, you just might want to look elsewhere....I usually get concerned if I can't find my male for a couple of days, and usually he is with eggs, to my delight...anyways...I am carrying on, enough...
