Horn Flower.
Hopefully someone like Maddy will come to the rescue.
I have a Horn Flower fish and at first it would eat frozen red worms, then it turned its nose up at that, then onto standard fish food, had enough of that and now onto fresh prawns! It would rather starve than go back onto food it once enjoyed.
WTF is going on?
