We have that book, and it may have been where we got our orig info from. Thanks for the heads up
On a separate note, our 2 mandarins were doing their mating dance tonight. It was neat to watch, but also a little funny.. they would swim up and intertwine together and sort of let their upward momentum carry them, but they kept trying to do it near one of our Vortecs, and would get sucked towards the pump, then would be forced to break away to sink down in the tank to try again. After about the third time I went out and shut off that one pump. I waited that long because I figured they would get the idea and try it in a different part of the tank... no such luck.. ok, so now the pump is off and they take a couple of minutes to get over seeing my ugly self lurking around behind the tnak (to disconnect the driver for that pump). they finally do their upward spiral again, this time srtaying fearfully close to the back corner overflow (yea, they just can't catch a break
). As they near the top they start to get pulled towards the overflow, but that isn't what breaks them up.. they hit the top of the waterline and break through the surface and pretty much freak out, separating and taking off in different directions, but leaving behind a cloud of what we assumed was eggs and sperm, which was quickly pulled over the overflow and down the drain (*sigh*... did I mention that they couldn't get a break ?). I waited over an hour before I turned the Vortec back on, but they never made another appearance.
But the cool part is that now we know that our pair is now truly a pair. It is soo cool to see them swimming around and hunting together. After several weeks this was the first time we saw them doing the mating dance.
I would have tried to get a picture of the dance, but they did it after lights out, with only the light from the fuge, more or less like twilight/dusk, which is when I read that they typically mate.
I will try to get some pictures of them foraging together this weekend, when taking pictures of our "take" from the swap
