Help! I was doing a water change and putting my thermometer back in. And it broke! I immediately took it out and scooped as much as I could out. Put my fish in the QT tank. Are they going to be ok? I am cleaning it all out and not putting the gravel back in. I only took 1.5g of water out to put in the QT tank. Can I put that water back in when I put them back in my regular tank? What do i do??? Will my fish be ok???
