We Can All Be Stupid

So I cleared up my community tank and decided to put in one of the male Dermogenys I'd had in a rearing tank. Within 5 minutes he'd been eaten by the female Nomorhamphus. Funnily enough (though not for the halfbeaks) I think this happened last time I put a male Dermogenys in there, but he disappeared after a few days, so I assumed he'd died (as halfbeaks do) and been eaten by the catfish. But this time, the "old girl" had a very big, very fully belly, so there was no questions about what happened!

So: note to self. Small male Dermogenys and big female Nomorhamphus do not mix. Funnily enough, she ignored the Nomorhamphus juveniles of similar size, and never ate a cardinal tetra when I kept them in there with her.

Cheers, Neale

Gotta lurn from somewhere, and it's best from some else

I usually separate my young half beaks from the adults because my female seems obsessed with eating them. I used to raise them up to a couple inchs and then try to add the females back into the tank and they kept disappearing. Finally I figured out that the large female was eating them. She doesn't touch the other fish with her but if I add any half beaks besides her male companion she kills them. She leaves the cherry barbs and Apistogrammas alone....
