Yes, Angela, and what's really odd is that the person that originally told me to put the frozen cube in the tank, is a college graduate of fish studies (sorry I don't remember his proper credentials), and he's now the manager of a very successful fish store in Sheffield, UK. The people that balled me out belong to an American forum (I won't name and shame that forum).
I've had some problems with that forum, and have talked to alot of people who have also had problems with it. Let's just say they aren't very congenial towards newbies, and not just newbies, but anyone that seems to have a different opinion than what they preach.
I will come down off my soap box now.
The idea behind giving the puffers the frozen cube of bloodworm was to help keep their beak trimmed because I complained that mine weren't bothering with snails and I was curious if there was something else I could do.
Sorry that I got off subject.
