Visited my cousins house yesterday and was shocked when I saw his aquarium, he has a huge Iridescent Shark in a 33 gal tank, the fish can't even turn in the tank, it has sores around its mouth, the water level in the tank is about 8" from the top and the filter and heater were both switched off. I spent the rest of the night trying to persuade him to let me take it when my 260 gets here and I would keep it in my tank until I could find a permanent home for it but he was having none of it, told me hes had it for years and it's still alive so it must be ok and he doesn't want to get rid of it and won't upgrade the tank either.. Really annoys me how the fish has to suffer for the rest of its life just because my cousin can't do the right thing and give it to someone who can look after it properly! Tried to get a pic, poor quality but gives you an idea of the size of the fish.
