Hello, my dad has kept various cold-water and tropical fish for a long time. His favourites are large fancy cold-water fish. He has a large good quality tank, and very good filtration and looks after it well. He buys large fancies, which are okay for a few months, then they go upside down for a few weeks, swim bladder issues presumably, before dying. Happens EVERY time, has lost loads over the years. He maintains the tank and filter religiously. I think he over feeds them, and feeds mostly flake or pellets. He gives them lots of treats, daphnia and blood worms etc. He enjoys them getting excited when he feeds them, which is every day. Never feeds so much, that food is left over. I've tried persuading him to switch to a plant and veg diet, including peas etc. Is overfeeding, or too much of a certain type of food the likely cause. He puts lots of effort in, but gets exactly same result. Not so much of an issue for his small fancies, always the large expensive ones. Please help with somefeeding advice. Are there certain foods that you can feed regularly, that are better for them? Thanks
