Aquarium Advice Addict
I added 3 new cardinal tetras to my QT tank Friday and this morning I could only find 1 off them. It occurred to me to check the filter and sure enough one was in there. It survived, but it is visibly injured. It's tail fin is missing. It is swimming and hanging out with the other one, but I'm not sure what to do. I can't find any trace of the 3rd one. I know I need to keep the water as clean as possible, but should I add some aquarium salt to the tank? Do a salt dip? Medicate? I have 5 endlers in this tank also. I really want this little one to survive. Any advice would be greatly appreciated.
