¿single Male Molly Wants To Breed With Other Fish?

[JoLtNbolt]

Tank Set Up
I have a single, silver molly in my 25 gallon community tank, with 3 female bettas, 6 Buenos Aires Tetras, and 2 gold veil angel fish. I had a silver female molly, but she died about 2 months ago.

Observations
This past week, I've noticed the male molly racing around the tank with his dorsal fin fully extended or flared out. He has also been stalking the 2 female Buenos Aires tetras, and occasionally one of the Gold Veil Angels. He tends to swim right below the female BA tetra, and nudges her belly... following her all over the tank until she escapes him.

Questions
Is this a problem? Should I go out and buy another female molly? Will a silver molly breed with other types of mollys, like gold dust mollys, black mollys, dalmation mollys, lyre tail mollys, etc?

Hi
Your molly certainly wont be able to breed with the BA tetra but I would get him a couple of female molly to keep him company and stop him stressing your other fish( though BA tetra are tough little fish)
A male molly will breed with any other type of molly as I have discovered with my molly fry.
If you only get 1 female he will stress her too much.I havent worked out how near your stocking level you are but with good filtration and water changes you should be ok
Ive read that mollies are quite social fish and like to be with some of their own species,as do all livebearers.
They can also be a little aggressive so thats another reason to add a couple of females
BTW--great info on the hornwort plant

What phenotype would I get if the silver molly crossed with a gold dust molly?

You could get anything unless the female has never mated before.Females can store sperm from previous matings and livebearers are sexually active from 3 months
My big lyretail sailfin female was green.From the 10 surviving fry I have 9 platinum with a few of them having a couple of black dots and Ive one very dark one.It may therefore take a few spawns before you get the true offspring of your male and female.

hmm well assuming I get gold dust females, which have only been kept with other gold dust mollys... what phenotype would I get by crossing them with my silver male? Would Silver be dominant or Gold Dust? Someone told me that darker is always dominant, but I wasn't sure because gold dust is so much more rare than silver.
