I guess I am supposed to reply if someone is digging up old topics........SO here goes ........Coral eating butterflies harm coral reefs.......so do bump head parrot fish ......Crown of thorns starfish and grounded oil tankers. It make no sense to me to collect more tangs instead of coral eating butterflies. Not from the perspective of the reef. Collectors will collect the amount of fish they ned to make a living, if you tell them we wont buy coral eating butterflies ...........then the collectors will collect more Tangs to make up the difference Most of the "hardy fish seem to be fish like tangs and groupers. Important partners of the reef . Trust me, tangs and groupers are far more important to the reef then parasitic fish like polyop nipping butterfly fish . Dont get me wrong, I dont import either of these fish for sale in my store .......not because of what the Government might think........... but because these fish make lousey pets. I personaly think MOST fish make poor candidates for pets. Fish that are known jumpers like blue dot jawfish or fish that terroriize their tank mates also are "UNSUITABLE ".......the fish too are poor choices as pets and should also not be collected. I think most fish can be grouped into some sort of category as to why each species should not be collected They fight---------- they jump ----------they dont last long------- they should be making babies {large fish }--they eat too much{hi nitrates} -------they need too large a tank------..........even Damsels have that nasty habit of beating the sh** out of each other. Should we as a hobby not continue to collect the number one imported fish.... Damsels? There is only one guidline the reefs waht us to follow........ We should only collect the species and the volume of fish and coral that wont harm the environments from were they come from..................

The butterfly or other reef fish that supposedly >90% die in captivity within 1 year, how long would they live in the wild? What is the percentage of eggs/larvae that survive and grow up to be fish collected for aquarium use? Doesn't someone now collect eggs or larvae on many species and raise these in captivity for the hobby, (thought I read about this somewhere)? Wouldn't more of this type activity satisfy many of the issues with collection and survivability in captivity. For example, if let's say in the wild about 2-3% (I don't know nor do I think anyone really knows the exact %) of the eggs produced by a given butterfly survive to adult fish, then if someone collected and raised maybe 20-50% of the same larvae and then sold these to the hobby even if most died within a year aren't we better off this way? With all the discussion in this forum about cyanide, poor animal handling, etc. , how many support and/or sell these larval capture fish, are they even available anywhere??

Dr. Regan Dufore has a system for capturing larval fish with large nets. The larval fish can be reared. He has been supplying post-larvae to SeaQuest for rearing. Blue tangs and some other species have been marketed through this process. In addition, the Taiwanese have managed to close the cycle by rearing some species of angelfish (P. maculosus, P. asfur) and other species (mostly groupers) from eggs, and marketed early-juveniles. I visited the Silliman Universiy Marine Laboratory in Dumagete (on the Island of Negros) i n 1987. Dr. Alcala demonstrated it was possible to rear post-larvae collected from nearby reefs areas. He reared over 100 species of marine fish in this way. I would support this approach. It takes some skill to rear marine fish in this way. I guess the limiting factor is the relative cost of the reared fish versus those caught as adults from the reefs.
