fish project

[lilme]

will a orange molly and black molly have a spotted orange molly or a orange molly and dalmation molly to get a orange and black molly

how to get a purple guppy
how to get a pink guppy

and on swordtails and platys
can you help pick a project on both

it will take many generations to get a strain of any fish
if you breed 2 different color mollies , the fry will have some of each color , some may be blended and some a pattern then you take 2 of these with the most of the color you want and breed them , the hard part is that you need to separate the female fry from the males before they breed to each other and that can happen before you know what sex they are , and live breeders can have more than 1 batch from each breeding
and it can take years to get a pure strain

You need at bare minimum for a Molly setup-
3- 20 gal
2- 10 gal
2- 30 or 40 gal

The 20 gals are for growing out males and females and for a single breeding trio or group with a ratio of 1m:4-5f
The tens are for newborn fry and a birthing/recovery tank
The 30 or 40s are for keeping separate large groups of males and females so you can put fresh genetics in every 4-5 months.

For a serious guppy setup like the one you are talking about you need to maintain two closely related strains so you can crossbreed to prevent mutation and unhealthy fish with deformed finnage.
So,

4-10 gal for growing out separately male and female fry of each strain
4-30 gal for keeping some of the best of each batch in reserve to add to the trios every 3-4 generations- make sure these tanks don't mix strains or genders
8- 5 gal for 2 trios of each strain and birthing tanks

Articles on proper husbandry can be found at guppies.com
Strains are very hard to develop and you need to start with high quality fish- NOT something from petsmart. Most LFS will take show quality guppies and pay a decent price too. Not sure on mollies however. I would do swordtails instead of mollies or platies.

Also, you have to keep the strains completely separated except for crosses every 7-10 generations. A good guppy setup requires about 10 tanks per strain.
