Black mollies and guppy's mating?

Question

I have 3 female black mollies
1 male black molly
3 female guppy's
2 male guppy's

They are in a 29 gallon tank, is this too big for them to mate in?? I want my guppy's to have babie's. I heard that both of these are easy to breed. Why haven't they mated at all??? My water is perfect and has a heater in it at 76 deg.

It also has 1 tbp of aquarium salt per 5 gallons

For those of you who made a comment about the SALT--- There is salt for Brackish fish that require salt and it is for FRESHWATER fish and it is 100% safe to use for them. Freshwater fish that are (Brackish) that means that they require 50% most freshwater and some salt. So don't tell me I am wrong, for the other's that answered me, Thank you =)

Answer 1

How long have you had the guppies and mollies? I think guppies take about 30 days for gestation period, I don't know much about the mollies as we only have a female and thus have never mated her. It could also be that they are too young to breed yet. But you're correct in that they are typically very easy to breed and if you are taking proper care of them (feeding, cleaning etc) then they should mate and give birth eventually. Just be careful with how much salt you put in, mollies are fine with salt, and guppies should do okay as long as there's not too much, but make sure that you don't over do it!

All I can say is good luck. I had a female molly that was bred before we got her. She had 30 babies. Unfortunately she and 27 of the babies didnt make it (I only have a 5 gallon tank). But the 3 remaining ones are doing good. But I did read that the females can continue to give birth for like 2 or 3 months after a male is taken away, because they store the fertilized eggs inside them, and that she will give birth about every month as long as she is bred. I dont have a clue on the guppies though because all of mine are males.

Good Luck

Molly, platty, swordtails, and guppy will all mate together. (They are all related to each other.) The larger the size difference the less likely it is to happen. Sailfin molly, and sailfin hybrids rarely mate with guppy due to size. Swordtail, and platty can produce offspring, but not the other livebearers. In fact most pet store "platty", and "swordtail" are in fact hybrids.

Answer 4

If a big tank is too big, then how did the fish they came from appear in the wild?
Anyways, try searching it on yahoo or google, type in something along the lines of "breeding black mollies/guppies" might help ya there.
I've never attempted to breed fish, so I really don't know. But a website may have a lot of info.

Answer 5

Make sure you have adequate hiding places for the babies, as both mollies and guppies will eat their young. I like to have a lot of anacaris (sorry it is spelled wrong) in my tank along with other live and plastic plants.

Answer 6

SALT!! These fish are freshwater, they should not be exposed to salt. You need to take the fish out and change the water. Doesn't matter how big the tank is, they live in streams and rivers naturally so they can breed in large areas--used to catch guppies in a big drainage ditch in Wichita Falls, Tx where someone had dumped them, there were thousands.

Probably the salt is the culprit. Also depends on how much protection you have for the babies, I have seen females give birth and turn around and eat the babies so that few survive, and they need lots of floating grass to hide in, or the other fish will also eat them. Female guppies are pregnant when you see their abdomen turn black--that is babies developing.

Answer 7

Mollies and guppy's mating is not impossible but its hard to mate them, even if you get success in breeding them then fry may be very deform or very week. So, if I was u I never try to breed them.

Answer 8

Just wanted to add that both mollies and guppies will thrive in saltwater.
