puffermama, you did not cause any problems at all, as grouperhead said, we can be rough, but it is only because most of us care aboutthese fish, not jsut ours but fish in general, yes some of us fish for sport and some of us hunt, but we all pretty much agree that when we bring home a fish we adopt it and wish all of them the best that can be offered and we want to make sure you know certain things, but are not trying to start things, believe me, i am one of the worst some times and it is generally b/c i have a hard time typing clearly wihtout always upsetting others but it is not out of spite or conflict at all
IMO, go for the 90 you asked about earlier

, the pufer should do fine in that, for now, enjoy the 30(for now though), and unfortunately i would not advize adding any ohter fish in wiht it though
