I really doubt the datnoid's ability to be able to actually successfully eat a ghost shrimp; he's barely twice as long as one of them and he always seems to try and attack them from the top, where he's unable to really get a good grip on the shrimp.
When he is hungry, he will know how to eat ghost shrimp. Absolutely.

Caught a few Mouth Almighty here in Queensland. Wivenhoe dam is a decent spot but have caught up north too. Got one in brackish water in a cast net with a bundle of eggs in its mouth (the eggs were stuck together in a ball, not individual eggs), I successfully transferred to fresh water and babies were hatched but unfortunately the babies didn't take artificial food and I lost them.

Are you the same QLD mick from the QLD fish forums? Mouth Almighty are all over northern Australia and PNG, they were translocated to lake eacham and have been thought to contribute to the extinction of Melanotaenia eachamensis in the wild.

Yer thats me. You on there too?
Here's some extra info, sorry about some bad quality pics but maybe people can get some useful info out of them.

I used to have an account, but it stopped working when they restarted the forum. Haven’t heard of that book before. I tend to use the blue Gunther Schmida book for my info on mouth almighty. Have to try and find that book you have

Thanks. Recently got ‘cold blooded australians’ of a website for $25 super awesome book with cracker shots of fish. He’s got shots of lungfish hatching, a Barra eating a rainbow and others.

Update:
The Mouth Almighty has successfully been feeding reliably on ghost shrimp, and so has the Datnoid. I'm probably going to end up clearing out one of my nano tanks and reestablishing it as a ghost shrimp breeding setup; shouldn't be too hard as I've kept ghost shrimp in the past before and they bred like rabbits. Unfortunately, the datnoid has somehow gotten ich and I have isolated him in a temporary 5g quarantine setup; luckily the main 75 growout doesn't seem to have other ich-ridden inhabitants and I successfully isolated the datnoid at the start of the illness. The datnoid is also still greatly interested in food, and other than having some difficulty swallowing ghost shrimp (he had the shrimp in his mouth for over three hours; still managed to gulp it down though) and lethargy, he's doing well. Still going to have to treat the main growout tank regardless, though- can't really risk losing any fish from ignorance. What's slightly worrying is that this is the first time I've had to deal with ich in ~2-3 years or so; last time I had a major outbreak and lost nearly all of my plecos and Mastacembelids, and I fear that I may end up losing the Dat and Mouth Almighty (although it's probably rather unlikely).
