I currently have a RTCxTSN @ 4", a Channel Cat @ 4.75", and a TSN @ 3.75". My LFS just got some Mono Pbass in the other day and I wanted to get a couple. My question is will the 3" Pbass be able to grow fast enough to keep from being food to the big cats? They are only $10 a pop, so not to much of a great lose if they do get eaten. So will they or won't they become a $10 feeder?
