just sharing picture of my aulonocara eating demasoni.. this is very weird because aulonocara are supposedly peaceful... unfortunately the aulonocara died also, probably of choking
This is a sad yet funny incident. The aulonocara is not known to be such an aggressive type. If you feed it 2 times a day, there is not any reason for it to eat the demasoni. May be the demasoni got stuck inside its mouth and in the process of getting free it went inside. Just a wild guess!
