Seaman said:The eel will eat them all. Trust me, it will probbably be a G tile if you get it from a normal LFS, and they will without a doubt eat the puffers, bumble bee gobies and the needle nose "gar" (From first hand knowledge...not with BBG's just F8's and needle node "gar").
The figure 8's if 2 inches or larger will kill the eel if you don't have enough hiding places for the eel. I would recommend scats or mono's because they are fast moving.
