If you have livebearers...

[Nancylm]

How do you stop them from taking over your tank?

 

[bigbanker]

All males or all females.

You can have a mix but cull the fry.

 

[Nancylm]

Is it easy to tell the sex? How do you cull? I don't think I could just scoop them out and kill them. Is there a fish that would eat them? I'd feel like at least that is the cycle of life... (I know, not really but I'd feel better about it)

 

[Wiggles24]

I am sorry but that is wrong, very wrong. If you don't want the chance of having fry then just get males.

Back to my previous question, then - is it easy to tell the sex?

 

[Cammywammy]

It takes a while to determine sex of fry until they mature. Depending on the specie most live bearers eat their young

You have a couple of options for the cull. Rehome/sell. Find someone who needs/wants live fish (such as Oscar or lion fish owners) and give them to them.

When my guppies bred like crazy I would feed the juvies to my cray. It IS the circle of life but a pain in the butt.... thus why my first options are all of one gender.

Males have a sword shaped anal fin, females have fan shaped anal fins.

 

[Scottyhorse]

On guppies, yes, pretty easy.

 

[bigbanker]

Re sexing: it depends on the fish. Usually super easy .

Great, thank you! I am sure if I didn't know how to tell the person at te store might try but could have made a mistake
