Yes I agree we are selfish, we try hard to keep fish and corals however, 20 years ago no one could keep coral or fish for the most part because not enough people did it and learned how. We are acting as an on going experiment and our experience helps those who follow in later years. Disease prevention, disease treatment, filtration, lighting, what we figure out will make a difference to someone in 20 years. That being said, Bob and I both had Rainsfords gobies at the same time, lovely fish, mine thrived while Bob's didn't. I assumed it was because of the number of pods in my aquarium but I found out later they need a heavy growth of filamentous algae, I didn't even know I had it????? Point is, with some precautions we can minimize the stress on the fish we choose to keep.
