Dallas is correct in regards to surface agitation and personal preference. On the other side, it's one of those items that could be useful in the chance you have to treat for ich using the heat method. That would also bring up another point now that if you're making up a list of things and you're going to the big box store that's having the $1/gal
sale, I would highly recommend getting a separate QT/hospital tank. Depending on the size fish you're wanting to keep, would dictate the size QT to have. Usually a 10 would be fair but if you can do a 20 I think it's much better.
