Alot of people do that. Buy the stuff and wait to purchase the fish. It's actually a good thing to do instead of jumping into buying alot of fish cause your excited. Just to find out too late that something was wrong with tank, or they are not compatible, and kill each other!I found a picture of my old buddy Bob who died. RIP. Doesn't he look like he was a sweetheart? Just look at that face!
Yes the lionfish are very cool but aren't they pisonous or something???
