Pet Forum / Aquaria / Cichlids / August 2004African holding fry
Is it the male or female that holds the fry in the mouth ? And from the time you notice it holding the fry, how long before the parent can no longer keep them safe in the mouth ?. I have one that is holding fry again and I need to set up another tank before I start to loose any. The last lot that survived (3-5 months ago) went from 18 to now 13 fry. So, how long do you think I have to set up this new temp tank. >Is it the male or female that holds the fry in the mouth ? Almost always the female. Paternal mouthbrooders are very rare. >And from the time you notice it holding the fry, how long before the parent >can no longer keep them safe in the mouth ?. Depends on the species. Some brood for about 15 days, some for about 50 days but most about 25 days. >I have one that is holding fry again and I need to set up another tank >before I start to loose any.

I usually try to keep her in the large tank until she is ready to spit the babies, unless she is being picked on, then I will seperate her earlier. I set up a 10-15g with water from the big tank, and set the heater to be the same (if you want to stay breeding, make sure you always have an empty tank and a cycled filter, once they start the just keep going!!) Put a sponge over the filter intake as well, so you dont suck up any fry. There is never liquid fry food in the lfs here, so I usually grind up my dry fish food (all the kinds in the freezer) in a coffee grinder for the fry, frozen daphnia is good and small too Good Luck Kelly > Is it the male or female that holds the fry in the mouth ? > [quoted text clipped - 5 lines] > went from 18 to now 13 fry.

The food part I have sussed out very well, boil a chicken egg, remove the white and keep the yellow, put it in a dehydrator, then grind it and feed them, it works 100% > You should be able to see in her mouth from front on as well, and be able to > judge if they are still eggs, or have developed into fry.

How long do they normaly stay as eggs before hatching ? > You should be able to see in her mouth from front on as well, and be able to > judge if they are still eggs, or have developed into fry.

It depends on the fish, yellow labs, haps and bumblebees I've bred held for 2-3 weeks, but brownae's and sp.44 about a week and a half. The dehydrator is a great idea, I've done the boiled egg in a cheesecloth, but it fouled the water so bad, I never did it again. good luck :) The fouling of the water is the moisture content of the egg, that is why you need to dry it out. I have been doing this for a while with other fish, including my salt water for the adult fish. Once the egg has been dried enough (not 100% dry) you can crush it into a powder. Once dry the egg keep well in an air tight container for months. As for feeding, I have a small plastic spoon with a cup size around 2mm, I put in one spoon of the dried egg. The other thing I used to do years ago with other fry was to put milk, wheat based breakfast cerial and a few drops of yogert (live strain) in a flat container, lay a few ice block sticks over the top and put the lid on and left it sit for a week. Small worms would grow and you would see them on the sticks, I would then wash the stick in the tank and the fish would love it. I haven't used this method for year as the smell of the decaying cerial and milk would make me sick. > It depends on the fish, yellow labs, haps and bumblebees I've bred held for > 2-3 weeks, but brownae's and sp.44 about a week and a half.

My fish had another round of babies again, this time 22 of them, over the weekend I made another batch of dehydrated eggs, 18 eggs all up, it filled 2 jars. Its 2 weeks now since they were born and they are now 8mm long, nose to tail. > The fouling of the water is the moisture content of the egg, that is why you > need to dry it out.
