I think other people should be allowed to suggest info to an existing profile, and the OP thats you Aquamonster, can decide wether the information is worth going in or if its just anecdotal.
I think as suggested by aclockworkorange we should add a section to the profile called
"Known Local Variants"
Similar species by Behaviour
Similar species by look
that way if someone liked the fish in question but felt it wouldnt work in their tank, they have some extra help in finding something similar
I do think this is worth doing, because I value the opinion and experience of members here more than a site profile because they all have conflicting information. which is why most of us post on here to ask others experience with fish even after we have checked out the profiles on other sites.
