Re: [anubiasdesign] Re: "False pregnancy" in dwarf cichlids?
- Well, after work today, she was back to her non-breeding colors,and the cories and ottos are swaggering around the tank like they own it, so whatever was going on, it is over.
Either she was litterally havinf a 'false pregnancy', or there actally was a clutch of eggs or even fry, but they have been lost, either to cannabalism or to the other tank inhabitants helping themselves to some handy 'live food'. Th egood news is that this golden dwarf pair looks to be a good match - so if I keep the live pushing the livefoods, they should be capable of doing it again.
Time will tell.

Gerald,Well, I have rather been hoping that there really are fry which she is so asiduously guarding, but if I have really missed them, then I am moving up my next appointment with the ophthamologist.Jim-----Original Message-----

No. I have seen a few cichlids guard other fishes' fry when their own kids were removed or eaten (I had curviceps that did this) and I recall reading somewhere about some cichlid (kribensis maybe?) trying to herd Daphnia after her fry were removed. But I've never seen or heard of "false" brooding behavior, especially if she's terrorizing the male. Could it be that your eyes, like mine, aren't quite as good as "in the rather distant past"? The color and texture of the gravel might also affect your ability to see them. They can lie very still when a huge scary head appears.

These were obtained as sub-adults at a stage where they could not be clearly sexed; as it turns out, I have two males and one female. The largest of the males quickly adopted full male fin structure and coloration, and began lording over to other two; the subordinate male maintained pseudo-female fins and coloration until I moved him to another tank where he has now adopted full male patterning. > > > Meanwhile, the dominant male and the single female began showing courtship behaviors, particularly after I began regular supplementation of their diet with brine shrimp nauplii and black worms. Being a teenager, and inexperienced with mating, the male's idea of courtship consisted mostly of briefly flaring and displaying to the female, and then chasing her about the tank when she didn't immediately fall into his fins in a fit of passion. Or it did until about 6 days ago, when he suddenly vanished from sight, only to be found looking very subdued in a corner behind the submersible filter. > > > Meanwhile, his mate was found in another corner of the tank, cozied-up next to an Anubias-covered driftwood which is behind a screen of chain swords. She was now a completed different fish. Gone was her usual drab coloration and meek demeanor - instead, she was showing that very distinctive checker-board pattern of a broody N. anomala, and she had become the neighborhood bully, going after anything that came within 6 inches of her - cories, ottos, or her boyfriend. The only fish she ignored were the cardinal tetras - so much for being the designated dither fish ... > > > OK, all of that is canonical golden dwarf breeding behavior, except that I never saw any clutch she was guarding, which by now should have hatched. This was a back corner of the tank, along a wall, and I didn't want to disturb her by moving anything in her vicinity, so I could have missed the clutch. Indeed, two days ago, and still showing her maternal coloration and behavior, she moved her guard station to a different site, under a large amazon sword, just as you might expect for a female shepparding a school of young fry. She was there this morning, still looking and acting broody. > > > Only ... this spot is right next to the glass, and I can view her and her surroundings very clearly, and there are no fry to be seen. I have kept and bred these little darlings in the rather distant past, but I have no recollection of having a female acting broody in the absence of a clutch.
