These are incredibly simple creatures. Some people seem to think they are difficult to care for. IME, this is the farthest thing from the truth. They can handle, and even thrive, in sub-optimal water conditions. I rarely, if ever, actively feed mine. They seem to get everything they need from light and broadcast feeding of the whole tank.
Completely agree... not exactly canaries in a mine are they?
I've had mine for about six years and it has split many times. They seem to split anywhere from 6 to 10 inches. It splits so often it's annoying- I've become very good at removing BTA's from rock.
