wow, thats pretty amazing. So i'm guessing no females around = no nest?
I've got my tank setup pretty much, just need to come up with some sort of filter-blocker to stop a mild current, also have a fake plastic planty + rock in there at the moment, but i'm going to pull the plastic off and put a real one I think.
I'm also 90% about getting a male, as I think this will be an easier option (just one) and I think that they are perhaps bigger in personality?
My LFS is getting locally bred ones this friday, going to pop in and get my little fella saturday morning, I can't wait!.
