This is very true. Ive kept up with most of Tay's posts though and her betta is very passive. Even use to chill with a group of cardinal tetra's she use to have with them so I doubt there will be a problem. Quarantine is a very good point also if I remember correctly Tay has a spare 20 gallon aquarium just sitting there so bases are covered this time around :thumbsup:
I'd probably QT them in the 10 since I have a filter for it already. The spare 20 doesn't have any equipment [yet
