My tank had about 10 Cardinals to begin with (bought the tank from someone else) with the move they were too sensitive and stressed to survive for very long. They were also about 3 years old, 3″ long. I ended up replacing them and bought 15 at once knowing some would die and have about 7-10 left and are about 3″ long. They are gorgeous and add such a vibrant yet delicate touch to the tank. However, they are VERY sensitive fish and any alteration or too much stress can send them overboard easily. Even the introduction of new fish incorrectly can kill them (I had that happen once). I’ll never go back to Neon Tetras after these guys.
Not an easy fish to keep. Very touchy to poor water quality, NO2 & NH4. Sad thing is people see these beautiful fish in the store and far too often attempt to keep them in a new tanks with the resulting total loss.This fish is for cycled tanks with good water quality. LIve plants a plus! No denying this fish’s beauty, but beware! Do not add chemicals to your water to mess around with ph, let them adjust to your local water ph. Unless of course you ph is way up there 8.0 + . Mine is around 7.6 -7.4 and they have grown large and healthy. Water changes a must and just a good idea with these guys. I keep neons and cardinals together and they simply outshine the neons in color. Cardinals can be dim-witted at times, definitly not as smart as neons!
I have found that Cardinals are much healthier than Neons. A nice school of these offers a beautiful splash of color to the tank.
