Okay, I have some Electric blue, and blue Gene dempsey babies. All are doing great except one EBJD. It is not eating, and hiding in the plants and leaves I have in the tank. I am not sure it will make it. I have read they are not a very tough fish, and sometimes get so big then hit a wall and die. How true is this, and can I expect trouble trying to raise the other 4 I have? I am falling in love with these fish, and am trying my best to grow them out. Any advice on how to get the little one to eat, or any other thing I should know, will be appreciated.
