New Colony

I have a few tanks with weanlings of the same birth date. I want to add a few males from one litter, and a few females from the other litters into a new tank; like a 5.10 and was wondering when is a good time to do so or what's the oldest that anyone has had luck?

AND...maybe throw the rest into a tank to be on deck for feeding. if they breed so be it cause I have a little guy that likes them up to pups.

I have searched almost everywhere and cannot find anyones experience doing this.

Usually if you just throw them together young they're fine.

I've thrown some together that are months old, and they fought at first, but if you flick the aggressor on the head to redirect him/her when they are attacking, it usually fixes the problem fast.

Lmao

Thanks didn't want to mix them too old and miss an opportunity while they all are only a month
