I've seen about 6 or 7 of them. I assume there are more that are too small to see.

Can someone confirm that these are not a bad thing to have around? My two clown and two chromis will munch on these things if they get hungry enough?

They are excellent to have and yes you will have a lot more just check your tank at night when the lights are off.

Yes your fish will eat them if they are hungry. Those are a good sign of a heathly tank as well. Congrats!
