I'm sorry, but that chart is not accurate, Phil. Where did you get it?
well, it's partially correct, except for this...
"Possession of the above species may be authorized as provided by Chapter 13 of these regulations (Possession of Wildlife, Scientific Collecting and Special Licenses) or Title 35, Article 80, C.R.S. (Pet Animal Care and Facilities Act), or as pets in private aquaria. However, release of any of the above species into waters of the state is prohibited.
Not true for private aquariums. I posted in the illegal fish response thread a while ago and copied and pasted the statute.
I highly doubt we would have a vendor from Colorado on here that lists Serrasalmus spp. in their stocklist on their public website if it were illegal.
