Issues With Cycling A New Tank.

[Fish are friends]

I recently aquired a 5 gal tank with 4 adult and 3 baby black mollies (i know far too much for such a small tank) when i went to pick the tank up from the guy , he had ignored my request to leave the tank and filter dirty and i would clean it, and he cleaned everything under running water....i have since added a second filter and added some mature filter media to the existing filter but the stats dont seem to change.

What i want to know is would my 90l have enough space to temporarily house the fish including the fry (2 that look like fish and 1 that still looks like a tadpole) so i can restart a fishless cycle. I have already added the largest molly to my tank a few weeks ago..

many thanks!

Yes, you can move them to the 90L, but there is a chance that the smallest fry will be eaten.
