Advice About Adding Fish

[fiskkeeperpro]

im about to add 4 fish into my new tank, ive added enough mature media from my old tank to support these 4 fish. Now, my question, how long until i can add more of my fish from my old tank to my new? My mum really wants to get rid of the old tank so she can move the furniture around

How long until the old media bacteria colonize the new media? I cant add all of the old media as there isnt room in the Juwel Filter, but i though adding the amount i have will be fine.

Thanks

Will

IIRC, it doesn't take long for bacteria to double in number. If it were me, I'd give it a week-10 days before adding another shoal of around the same size, just to play it safe.
