Black Mollies as clean up crew?

[farfromsea]

Well I was reading again and I think my initial source was garbage. Apparently a study showed that the ideal salinity for breeding is 25 ppt based on # of spawn released and fry growth rates. http://cmsadmin.atp.co.il/Content_siamb/editor/57_3_Vasagam.pdf

I keep mine around 35 ppt (1.025) obviously but I'm not here to raise 100s of mollies lol.

Some places say the lifespan is unknown and then this site

says the males get sexually mature in less than a year and then die one year(ish) after maturity so I'm not exactly sure what the juvenile period is but I guess we can safely say 2 years max for males. I would be curious to have someone do a study on the lifespan of mollies at different salinities versus like you're saying a lifespan of mollies when they move between different salinities.

I'm curious about the 5 of live young that survive in SW

I just toss in the orange sailfin ones and they do fine for the most part, in the wild they can have big salinity swings sometimes and adapt well.
