So I am the average aquarist that falls into the category of mesmerized by angelfish. Before I had known about cycling tanks and water chemistry, I had bought and killed an angelfish due to ammonia spikes and overstocking, and so forth. Now I am very knowledgeable in water paramets and so forth... But I wanted to know if there was any strain/breed of angel that was stronger than others, and vice versa. Thanks! (also if certain strains have different behaviors, requirements, etc) [probably not but just checking]
