beyond that, i have had a fish sit in a QT tank for 6 weeks, watched every day. on the final day right as i was setting up acclimation buckets to transfer, Ick finally reared its ugly head! so thank goodness i had been using a QT tank, and followed the rules about QT periods (the proof is in the pudding), and that i saw it before the transfer. Unfortunately it was another month in the QT tank before that fish could be added. this could have been avoided if I Hypo'd from the beginning. Subsequent fish, i have just assumed that the fish from the LFS or from the mail shipment HAVE ick, and performed the process, being right 3 out of 4 times.
anyway, this is not a thread for steadfast rules, this was a section for tips, and i think it is a valuable one based on experiences. But lion is correct, you dont HAVE to do it, it's not a necessity.
I agree. Like I said, it cannot hurt, but I just wanted to point out that it is not absolutely 100% neccessary.
