My flowerhorn fish looks like she is about to die & is acting like she is severely sick please help!

Question
Hi I have a flowerhorn fish who is about 5-6 in. big living in a 120 gal. aquarium we've had her for about a year she has been doing fine until yesterday when i woke up and saw her frantically jump up as fast, as hard, and as high as she can and hit the lid of the aquarium and the wall as if she had a seizure and then she sunk to the bottom and layed down flat on her side at the bottom of the aquarium she has been laying down on her side for two days now
she tried to swim once but she can't and when she does a little bit she sinks down shes still breathing and moving her gills even thou today she was breathing really hard she also periodically jumps frantically as if shes having a seizure and hits the lid and the wall like I described before (she does this at least 7-10 times a day if not more) and just sinks back down and lays flat on the floor sideways and today she started on and off loosing her color and turning  white and her eye turned from black to completely bright red and then she comes back to normal color and does it again after awhile....I do not what to do I just changed the water too I'm so worried I brought the fish as a birthday gift to my wife and she has become a part of our family and we're all devastated especially because she is so beautiful I'm willing to do anything and really hope its not too late please tell me what I can do !

Answer
Hi Michelle,
I'm so sorry to hear about your flowerhorn. What a shame...

Unfortunately there is not much you can do but hope that she will recover. The sudden jumping frantically is probably a nerve issue or a panic response. It sounds like there may be a head injury that has really put her down. I'm really sorry to say this.

I once had a very large (8-9 inch) tinfoil barb hit the top of the aquarium very hard and he swam about frantically for many minutes and went into panic... Sadly, later he died the same night. There's nothing you can really do.

But all you can do is hope. You never know when they may recover. The fact that she hasn't died yet--Maybe she can get better and recover. The damage must not be extremely bad for it would have killed her by now I'd imagine.

Keep up hope and best wishes,
Karen~
