Angel*Fish
cats and large squashes
Why is the impetus on me?The impetus is upon you to back up your claim. YOU claimed that they are notorious for being cyanide caught. Based on what? Also, he made no reference to where his angel was collected so we have no reason to assume that his angel was caught using drugs.
It's pretty well known that most of them come from Indonesia and the Philippines. And in those countries juicing is rampant in spite of being illegal which means they are also illegally imported in the US. If you speak to someone who's had success with a bicolor, they will typically say they did nothing special and often may not have even been aware of the poor survival rate of these fish. They just got lucky and got a healthy fish.
