Yeah, I've got three breeding quality males and two with massive kinks in their tails which won't be fathering anything...and one scrawny-looking female. I keep them in tanks with other fish - dwarf loaches and a borneo sucker - and haven't had any issues with them being eaten...so far. I definitely wouldn't mind coming across a few more females at the local petshop though, every now and then someone delivers a fair few and they all go pretty quickly. The only problem for me, apart from the fact they eat their babies, is that the females seem to very susceptible to the slightest stress (being hassled by a male perhaps) and end up suffering for it, whereas the males stay bright, active and completely healthy.
