The big green Haddoni that has been at the greenhouse and more recently at Dan's house has been at my house for about 2 weeks. It lives happily in its' flowerpot and has been growing/expanding daily till this evening when it apparently reached its' goal. It has grown to nearly 20" across and just released a huge sperm/egg bundle which of course has clouded the water and made it kinda musky smelling.
I got some video of it- I'll try to post some.
I wonder what effect this will have on the other Haddoni- a nice blue one that's much smaller...
