I saw that filter you purchased in the other thread and it looks good and oversized, so filtration should not be a problem for your fish population.
My concern would be the space available for the fish and whether they could be stressed out when they all reach full grown size.
Other than that, keep an eye on the water quality levels, and you should be good to go.
