Okay, see the fish in my avatar? I just saw that gudgeon spit out the last two inches of horsefaced loach left. Just the tail and some body. What loach won't fit in the gudgeons mouth, and will be okay in a 55? ------ < Is width of mouth, and it's almost as tall as that. Good thing I like the gudgeon, too bad for the loach. "Why couldn't he just stay under the gravel?!?!?!!? 
If your thinking that I under feed them, your wrong, the gudgeon is always hungry, although I doubt she killed it 
Could have been
3 pictus cats Prime suspect
1 ropefish Nah
1 geo surinamensis Probably not
1 Severum Doubt it
1 butterfly fish No way
1 rainbow cichlid Maybe
or either of the 2 gudgeons Possibly
I'm off to solve this
