Need Advise in Breeding Black Mollies


Phenomena

Recommended Posts

Hi All,

I have 7 black mollies. There are 2 males and the rests are females. They're adults but there's no sign of fry. Do they need special condition to breed?

- They're in a 4x18x18, filtered with AC 500, bare tank with some PVC pipes

- The PH is about 7.5

- Eat a lot

Thanks guys, :8

I think your fish may be eating the young. When they are released they will "normally" make for the top of the tank. Use some floating plants or something to provide shelter for them up there.

I've always found mollies breed better at a salinity of 7-10ppt and high iron levels. Hope this helps.

Hi,

I agree with Adam about adding salt to the aquarium. I also found that a higher pH and hardness helps. Also lots of greenery, esp. floaters. Try adding some coral sand/crushed coral/limestone to the aquarium.

yes listen to all these people, i had only 2 mollies and i couldnt stop them from breeding, they were constantly havin babies. Make sure u add that aquasonic tropical stuff to increase hardness, it has all ur salts and minerals etc and i had temperature of 28 - 29 and they loved it. Add plenty of plants! and feed them well and generously

Hi fellas,

Very much thanks!!! I'll try to increase the PH and add some salts and plants.

Will plastic plants work? What sort of floating plants that's hardy? and where to get them? I rarely see floating plants in LFS...

Thanks again...

higher temps for a bit 28 or so.

salt. definitely salt, i was reading an old book that said mollies were found on the east coast from south carolina all the way down the coast of s.america. even out to sea...

lots of plants!

consider using a dropping tank - a small 18" so that she can drop the babies in some peace. Although being back it's going to be harder for you to tell when she's ready.

a little bit of trauma can help them bring on the babies too. put her in a bag and carry her around the house for fifteen minutes or chase her around the aquarium with a net she may decide that losing some excess weight is a good idea, and could well end up dropping them a few hours later.

cheers

Having bred over 1,000 of these little blighters over the past 6 months, and having kept them for over 10 years, I can tell you first hand adding some salt does help, about 1tbsp per 2g (8L), a temperature of between 25 & 27c and as for the pH, well the high pH story is a myth... in actual fact, 65% of the Central & Sth American Mollies live in 7.0 to 7.4, so a neatral pH is probably a better option, and easier to maintain...

Now to get these little suckers to breed, try dropping the temperature of the water when doing a partial water change, say 3-4c lower than the tank water, and another trick is the use of an active iodine additive, such as found in many Black Water treatments, this is achieved by the fishes natural reaction to active iodine promoting the spawning cycle and adds organic colloides which is a protective inhibitor for the fish... in other words it is like a multi-vitamin with Viagra added... YIPPEE...

I mainly keep Yucatan Velifera (Giant Sailfins), but have quite a few Blacks and Dalmations as well, add to that some Swordtails and then my exotics... Leopard Discus, Peppermint BN's and Zebra Plec's plus too many others to mention, it leads to all sorts of experiments with water paremeters, thats how I came to the method mentioned above...

Good luck

Just a couple of quick questions :wub

How many fry on average will a black mollie produce?

Will they eat their fry ?

I just noticed that I have at least 4 baby black mollies in my small 38L self contained tank. Judging by their size I wouild say they have been there for about a week. As there is only a few I'm wondering if the parents ate some, or maybe they were sucked up into the filter??? :B:

Or perhaps they are just hiding from me :D

Cheers Adam
