Re: pure vrs tiger
Yeah, after a while you learn to tell them apart pretty easily, unless they are small, then they look similar.
I don't bother to check, but pures have no scales on cheeks. Pike do, think tigers are partial. Generally fins are more rounded on tigers, but that isn't always so. Pures usually seem brownish or greenish brown. Tigers more pike colored with very light silvery sides. Basically, more you see the more you notice.
There is always a season!
