Add now, or later?

I've got 4 adult(ish) peppermints and a few smaller albinos (in a smaller tank)

Whilst my peppermints are shyl hiding away, shall I add some of my younger albinos to the tank?
Rather than add them when they are older.... as it may cause problems!

I was thinking if they could settle in whilst the younger ones are in there, it would avoid any territory issues if I was to add a few when they are older as my breeding caves have just arrived! (four of them)!

I would only add about 2 or 3 small ones, not the tiniest ones!

What do you all think?

I say go for it!! as long as there is enough room for everybody and hiding spots and so on they should be fine I think.

Thanks! Ive added one and hes doing fine so far... when the others grow a tiny bit more ill add those too

I post this same question on a different forum and all i got was people argueing over cross breeding bristlenose :S Hmm..... Last time i checked.. peppermints cant breed with the common bristlenose.

Some people! lol
