Ok, so I have an 8" buetti in with some bichirs that I'm sure could eat it, including an almost 14" weeksii that looks about 3 times as round. They've been together for like 6 months, but there was less size differnce when I got them. The problem is that my other bichir tank has smaller bichirs, the smallest being a 4" albino sen. What do you think I should do?
