I think we should leave things as it is. Too many changes will be a bad thing at the end. 1st we ban big fish, rare and exotic. Next thing you know, something else will be ban.
What if i say we should ban all tropical fish etc. since too many them getting kill because people cant keep them long then 1 week? Or maybe we should ban all feeder goldfish, rosy; since it cruel. They all bunch in small space and we see their life as meaningless since "they just feeder"
Got my drift
