I don't know a huge amount about them, but I've read a fair bit on another forum from a couple of ppl who have them. They prefer company, they're definitely not happy on their own, so if you're thinking about getting any at any point, you need to prepare to have a tank big enough for a group of at least 4, more like 6. They're very sensitive to water conditions, it doesn't take much for them to react badly to even minor variations. They can stress quite easily too. It takes them a while to settle into a new situation and a number of ppl have lost one or two in the first few days to what they can only put down to stress.
They're not an easy cat to look after

But seriously cool-looking
