i think youre ok. i never test my water, never acclimate the fishes. i just dump them into my tank. my ember tetra started playing with itself the first day. just dump it in and dont think about it too much. fishes will live. your water gotta be really messed up to dump them in and they die. even brackish water fishes i just dump them in. even when adding tap water without treating the water it's fine they wont die.
