LOVELY PHOTOS!!! And the little VWBug ornament is so cute... is there a story behind it, or did you just like the look of it?
As long as you keep a close eye on your pH/nI/nA stuff, your goldies should be fine. Ours were always tough-as-nails when it came to new aquariums. We kept a trio of them when I was 6-12 in a 15 gallon tank. Yes, not the best arrangement, but back then we didn't exactly know any better. Anywho, they were hardy as hell until my baby sister (only 2 at the time) dumped a whole can of fishfood in with them. O___o;;
So yeah, keep an eye on them to see if they seem stressed and monitor their water cycling and all should be well, methinks!
