Out of 1000 fish sold retail......900 will die within the first year? Now lets say we limit those 1000 fish to only "hardy types" like groupers and damsels? What fish have a better survival rate then those? Well, if we were to follow the life of those fish after they are sold to the hobbists, we would find that one : most will still die within weeks in over fed "death"tanks,"Hardy" or not.... the lucky thirty percent that might make it past eight weeks are soon too big {Groupers} or "not exiting enough" {Damsels} And what we have left are unwanted fish with owners that are looking for new interesting fishes {butterflies?} to replace the Boring {"Hardy"}ones? If we cut in half the types of fish taken from the reef, this will mean having to double the numbers taken of hardy species.twice as many Groupers ,Damsels, Triggers etc.....Its the difficult, odd fish, that on one hand keep us from depleting the supplies of the limited variety of hardy types and on the other hand is not learning how to keep seemingly impossible fish and corals is WHAT this Reef Hobby is ALL about! Yes? No? Since not long ago almost ALL marine corals and most fish were deemed imposible to keep, lets say we use the past as our starting point to decide what to ban and what not ?{All Corals and most fish} Silly? As silly as it would have been then, twenty years ago to ban and not waiting until now to conclude what to ban? How bout we Again wait for future strides in Marine husbandry to determine what is possible and what is not?
