Single post in Shroom's Guide to Fishing

Hey, thanks for the guide! I had a quick question - are there pokemon that are only available from fishing and don't show up as eggs in the lab? There's some fishing pokes that I've never seen in the lab, but I've only been playing for a couple weeks now, so I'm not 100% sure if that's really because they're only from fishing or if it's coincidence. I didn't see anything about it in the wiki so that might be useful to add if it's the case.
