I heard guppies were the quickest...but mollies and platys are cheaper :screwy: Which fish has larger spawns?

Yes I'm cheap :P
 
guppies breed every 4 weeks, mollies breed every 6 weeks, platys breed every 8 weeks. i would think the brood sizes would be mollies have the biggest, then guppys then platys but thats just based on size.
 
it all depends what you are using them for. since you are posting it on here for cost effectiveness, i'm guessing they will be feeders. i would say mollies would serve your purpose best. platies and swords take longer to breed and grow. guppies are fickle and die fast. mollies will breed fast and grow relatively fast. i have heard you will get better results in breeding mollies if you put them in a slightly brackish setup
 
mollies best in my experience dont know if its fish stocks here but a: mollies are cheaper to buy in the first place and b: guppies round here carry a lot of disease and seem to develop disease rather easier than mollies c: mollies have larger broods also in my experience and easier to keep alive with some cheap floating plants or water wisteria. the biggest molly i had when breeding for feeders was 7 inch long the biggest molly i have seen she was a battler used to own the tank.
 
also yeah millies go mad for salt my friend uses them for maturing his filters in his marine set ups. i never used salt but heard it does make them more active anything from brackish to full marine.

They can tolerate freshwater to saltwater well. It does not mean it is necessary to add marine salt in your tank especially when you have other fish in there that will not tolerate the elevated salinity. As long as the hardness levels are high in freshwater setups, the mollies will be fine. It's the soft water that you should watch out for. I had two black mollies intended as feeders to my lionfish a few years back and they survived predation for nearly two years before I quit SW.
 
Every Molly I've ever bought has sprayed babies all over the tank by morning. Must be something about being transported and put into different water.
