Apistos are fun! I've messed with a few species, if you can get them home bred in the US, it's paramount. Pay the difference. If you can't find any, grow some up and spawn them for the 2nd generation. Imports don't seem to last long, from my own experience and several others I've talked to at the Charlotte Aquarium club. Subsequent generations are hardy and perfect though.
Nothing good happens fast in an ecosystem.
