Thatās crazyWhen I started to seriously keep fish, it started with Mollies and they were quite simple to breed....literally just put males and females in a tank and they just bred. Chalk it up to ignorance bliss, beginner's luck, or whatever you want to call it, but it was the early 90's I was a teenager, I bought a 10g tank. Got a few Mollies, they bred, bought more 10g tanks a few more times as they kept breeding. I had probably 5 (10g) tanks filled with Mollies. And this was before MFK and just the beginning of the internet, so no...I didn't properly take care of them....100% water changes every 3 months, didn't add salt to make it a brackish water tank, I think I remember adding aquarium salt periodically. They literally had gravel, a fluorescent castle, and fake plants with an UGF and I don't even remember if I had a heater yet.
Should I deworm them, the ones I got are still in quarantineJust make sure your Mollies are free of Camallanus. Unfortunately a lot of the Mollies available are infected and not properly dewormed before they are sold.
What does that mean?For the beginning stay away from the large sail fin varieties. They can be quite problematic. For any other Molly it's what the others already wrote.
Yes.Should I deworm them, the ones I got are still in quarantine
The big sail fins are P. velifera, P. kykesis and P. latipinna. They are way harder to keep and to breed in prolific numbers than the other Mollies. They tend to fall ill quickly and to show dwarfism and other genetic problems after only a few generations. Sometimes the F3 is already heavily affected. Them getting sick often is also somehow the reason for many people believing mollies need salt. Though they can live in pure freshwater habitats in nature, they often seem to do better with salt in the aquarium. Which prevents the outbreak of some diseases and makes them grow better but also tends to decrease their lifespan.What does that mean?
