I bought this Mel. Chipokae once and he was viscious. All he would do is swim back and forth terrorizing my Elongatus, Kenyi, and Crabro so much I had to take him out. My Kenyi actually held her own for a while, sometimes even chasing the Chipokae, but after a while her spirit broke and was a victim for the rest of the time the Chipokae was in there.
