i have homer simpson starfish in my tank. looks like nuclear radiation
inflicted starfish. some have 3 legs, some 4, some5, some 6, some 7, some
maybe more, or less. one is in half, and ive been watching him grow for
years, hes now bigger than a pencil eraser, hehe. some are about 2/3rds of
a starfish, wierd. i hvaent seen any more micro starfish, i think they
came from a big spawn that was on a live rock when purchased, any ideas on
this? will they spawn again?

You are talking probably about Asterina spp.
Starfish like these reproduce by fission.
After dividing they regrow missing parts...
If you look closely at your 1-2 legged ones
you should notice very small leggs growing in
the place where you think there is missing one.

I have them in my tank - some people think they eat
corals, but the ones I have in the tank are harmless.
