sooo... then you would think the selling of seahorses, discus, nugget plecos, and all other hard-to-keep fish unethical?
no, fish that are hard-to-keep usually just need specific conditions to thrive, provide these, and they are fine, i dont think that dork is buying a great white!
dork said that he did the reasearch, and if he can meet the conditions required, and is ready for whatever fish's needs that hes buying, then he should go for it!
