webs that come out at night???

michaeltwana · 01/28/2007, 10:00 PM

I have thes worms, I think, of some kind that send out these long up--to 15 inches or so--web like strands only at night or when the moonlights are on. What are these things? and what should I do? should I be concerned??

thanks as always

no i don't think so---also i forgot to mention it only happens on leathers--sinularia and toadies

soft corals use mucus to remove stuff that has landed on them, how much flow do you have in your tank?

Vermetid snails perhaps.

nope---these things are reaching out and dragging back in..they are reacting to light and to touch...

what was the answer?

michaeltwana · 01/28/2007, 10:58 PM

sessile ctenophore...i guess they are harmless

Most Ctenophores (pronounced "teen - o - fores") or "comb jellies" are small to moderately sized pelagic animals. Although they look superficially like jellyfish they are not at all related to them. Most forms have two long tentacles and the tentacles always have a fringe of branches on one side of them. They use these long, extensible tentacles to catch their food. Unlike jellyfish, they have no nematocysts and use glue cells ("colloblasts") instead of nematocysts to adhere to prey. Some of the odder ctenophores are sessile and look rather like flatworms. These crawlers are typically found on soft corals or gorgonians. They are harmless, but they reproduce so well in some aquaria that may become abundant enough to be pests.
