@crinrict It would appear this bug has been fixed :D One of my members said so, and I went to test it myself and had no trouble catching them at level 10.
Just did further testing and this affects Rainbowfish as well. It certainly makes Fishing more profitable to be able to catch sturgeon, treefish, batfish, etc. more frequently, but this seems like a definite bug. I just jumped back to 10 and am now unable to get Tilapia and Rainbowfish from the waterfall at Sylvan Glade.
This would explain a lot towards why my fishing collection isn't yet complete given how many hours I've invested in various locations around the maps.
I did not add Tilapia to my collection until I added a new sim to my household and he started fishing and got his fishing to 4 or 5 last night or so. I have had catfish forever somehow and am quite certain I stopped catching it because I remember in the gardening guide you mentioned catfish for fertilizer and thought great I'll look for that but never saw more than the one or two I initially caught.
