WORMS?? good or Bad??

[mr_alberta]

Without a picture its hard to tell exactly which worms you are talking about, but its most likely a Bristle Worm (spikey) and possibly a Peanut Worm. Both are mainly harmless though bristle worms can cause problems with their spikes if they get really big.

As for starfish, its hard to tell. They usually drop legs before they die. Starfish are notoriously sensative to Salinity and once they start to die, there is very little you can do to stop it. If you do a quick seach on the forum here, I'm sure you can find much more info.

how does a bristle worms spikes cause trouble? are they venomous?

yes they are venomous; dont handle them bare handed. They only actually cause significant problems in about 1 in a thousand tanks though.
