One of my communal tanks has 2 Synodontis euptera in it. With a Pleco (yet to be identified L2something) & kribensis. I am trying to get the Krib's to breed again, after "Big Boy" Pleco snuffled up those gorgeous eggs the first time. One of the syno's is a lovely chap, comes up & says hello & asks for food etc. The other, the biggest, is a total turd. He fights with the smaller syno, he steals food from the pleco's mouth (& has felt those barbs almost daily), he stabbed to death a former male breeder Kirb, with his tail & he hates to be seen... "monster of the deep" I call him

The problem is, my only breeding male Krib left has disappeared!?!? He was there & I went to work & he was gone???
It's been 2 days of no sightings AT ALL?? The gals are still there & healthy & no diseases. So I have come up with only one theory (after searching around my tank to make sure male isn't on the ground somewhere). My theory is that "monster of the deep" ate him??? Monster is around 3.5 inches now, he doesn't like the Kribs because they're so aggressive to him, he eats like I never fed him before (although i've never seen him poo) and he would probably do it just because he can... ??

But there is absolutely no sign of a Body. There is only 3 female Kribs- not enough to have eaten their whole buddy in a few hours & they've never eaten any other tank mates who are doing the "final float"

So like I said- My theory is Monster of the deep ate him in a jealous moment??
Anyone wanna argue or support my theory??
