Your picture of Neons are actually Cardinals, how do write an article on Neons and post a picture of the wrong fish, especially after you described their markings? What could have happened, and what should I do now for future fish? Originally Posted by darkmule What do you think may be the cause, a disease, a bully in the tank or the filter killed him??

Now my neons are healthy, have bright colors, and growing well.
I hope this helps!!! My original neons are doing well in their combined tank too with no problem. Reply lizzy Feb 24, 4: Happy fish keeping everyone! Fish that mix well in an aquarium are guppiesother types of tetras, such as the rummy-nose tetracardinal tetraand glowlight tetraand other community fish that live well in an ideal tetra water condition. This can be done simply by letting the bag of Neon Tetras float on the aquarium water.
