I agree, lets chill out. Jillian, David has said that he has removed many of the initial fish involved. And I don't see how LR is an issue? Don't take out the LR, just chose the appropriate fish.
The point that this is a rather small tank to begin with is important to respect...lots of LR makes it smaller which means that we are not looking at adding too much considering there is also a porc puffer in there already. There is no problem at all going aggressive and I don't think anyone was implying that (though I would disagree that it is the only way to go
). Just take into account here that we are not looking at adding many fish to this tank because of space restrictions, knowing what we know about the bioload and general size of aggressive fish.
Based on previous threads, David, people are concerned. But the emphasis is now even more important...you will not get as many fish in there as with community, and it becomes very very important to abide by this as aggressive fish can be messy eaters and send water quality a bit wacky quickly. You had some problems previously, but this is a new start.
It is just important to start off in the right way. Many things like triggers and groupers are very small when they are sold, but they will get large (fast) and many stores will not take things like groupers back. The decisions you make now will be very important. Do you have definitive plans for a larger tank?
Perhaps, with a porc puffer already, you may not wish to add much else...so that you can stick with the 55 longer, or you may need to watch it with adding something that can be a little high strung.
I wouldn't, however, get rid of LR. It was only mentioned because it limits the space available. LR will be very important. It is important in any salt water tank.
