Absolutely! I have the cure! Ready? Forget about it. Thats all I can say. They will get drop eye almost always. Arowanas get it in the wild and in your fish tank. It is not a disease, it is an arowana. Thats what they do. To much time is spent worrying about this. Just love your fish. I HAVE seen severe cases in older arows but in young ones, to me, it is kind of cool. The blue color on the top of the eye looks neat. The other eye will catch up. It just seems like a distraction to worry about this. It doesn't hurt the fish. It doesn't effect their ability to hunt. It doesn't effect their ability to attract a mate. And (to me) it doesn't effect their status as one of the most graceful cool fish in the world. To many people are making to much of this, putting ping pong balls in the tank (you've got to be kidding), Hell throw a basketball in there, maybe that will help. You need to look at it as thats what the fish do. They get "drop eye". I don't even like the term, as it implies there is something wrong. I'd rather say "as arowanas mature, there eyes begin to drop, giving them an even greater menacing look than they had as youths". There, did I fix it?
