Well, after doing some research, I decided to go ahead and dose the big tank with both Pimafix and Melafix. Will dose as per instructions. And since I don't use Carbon, no problems there. From what I've researched, shouldn't hurt anything in the tank, and help those that need the help. I did an ammonia test on the 10G, was over 2ppm this morning when I dosed, and now is about 1ppm. So I'd have to wait til tomorrow anyways before moving the fish. If it was anything else, then I'd definitely move the fish and dose, but being Pimafix and Melafix are natural remedies, and not real meds, will keep things as they are.
Once I get all my stuff in that I ordered, will set up the 29G with an instant cycle, and move my Bolivians over. After thinking hard about it, I'm going to go ahead and move all 3 over to the 29G. Then keep the GBR's in the 75G. Will also move a female BN pleco over too, but not the one the male is chasing, hehehe. Then I might add a few pencilfish, as I believe I was told they won't bother the eggs or fry. Just something to give the tank a busy look, but not overdo it.
