will little sickly bubble grow new corallum? how long would that take?

ok, i know they say that these don't keep in reef tanks, but here is one that i've had for 11mos and it is growing nicely! i just noticed a new branch forming from a lone polyp the other day. so that's the good news. the bad news is that anything that I put it near that isn't a soft coral...

using sand, but put cc in tupperware on tank bottom for frags. ugly, but it only takes a week for them to grab a gravel.

i've found putting cuttings in gravel bed, let them pick how to stick and then putty gravel to rock.

i agree w/ waterfaller

how small is the worm, any more description? what type of polyp? does the polyp still look ok? daytime or night?

could do, but some are growing on corallums so this would be a temporary fix.

manual removal is very difficult. when i try, the worm receeds into its tube, when i rip off tube it cracks and thousands of little bits fly into the tank, and it seems this aids in their reproduction.

they are not apstasia, though are the same color.

Who eat's these. They are small colonial brown duster worms that live in calcerous tubes. they are kind of pretty but I think they have begun to grow out of control. They place a high calcium demand on my tank so it is hard to keep even Ca levels. I also think they may be stinging corals. i...

are arrow crabs nocturnal? can they be removed? my fish are expendible for the sake of my corals. actually i still have a damsel in there from the birth of my tank in '96. i would prefer to see it dead!

behavior is typical. the fish is making a nest for itself. when finished will look like indentation in sand and the fish will hover there and protect his territory.

they are pink, somewhat wide and quite bristley,white bristles. in the middle of the worm it is dark.

i've had an infestation of bristled worms for about six months now. I don't know how to get rid of them. they are nocturnal and abundant, should i worry? all of my corals seem healthy and growing.
