Which corals are being destroyed by illegal collections in order make jewelry?

Fire corals, or stinging corals often produce a painful burning sensation when touched by bare skin. They usually grow in branching, blade, and box patterns. Lace corals are profusely branched, hard, calcareous skeletons. They have both sensory/stinging polyps and feeding polyps. The identification of Fire corals by color is not always easy. They tend to look like dead corals, since there is no visible tissue, fleshy polyps, or mucus. Furthermore, there are no defined cups (corallites) as found on the true stony corals (scleractinians). However, all species tend to have a characteristic white edge or tip that serves to warn the unwary that these corals are not to be touched.

What type of corals should I get?

All corals have different requirements in terms of lighting, calcium and water movement. However since this is your first marine tank I would recommend soft corals and some mushrooms or zoanthids. These are fairly easy to keep and are not too demanding in terms of light and calcium. You should be able to grow softies like Sarcophyton sp., Sinularia sp. and Lobophyton sp. under T5 lighting, and this will also suit the Mushrooms. For water movement you should aim for a tank turnover of around 15 times per hour. As your tank holds approximately 120 litres I would go with two powerheads capable of punching out approximately 900 litres per hour. The price depends on the species and of course the size, but a small frag should cost somewhere between 10 and 15 (or about $20-25 if you are in the US) whereas a fully grown coral could cost upto 50 (approx $100). I would just start off with 3-4 corals for now, this will give the corals room to grow and put less demands on calcium.

What lighting is best for corals?10 points best answer?

I would go with coralife 20w 50/50 bulbs if I were gonna use anything of this type. These are expensive though. about $30 each. My solution, Two clamp on desk lamps with 27w 6500k CFL bulbs. You will get evaporation this way since it leaves you with an open top unless you have a piece of glass cut to fit over the tank or something. The glass would be advised as any good light would leave you with an open top. with two 6500k 27w CFL, you can do pretty much anything although I have not tried SPS. Softies, shrooms, and Most LPS would do good. You wo not have the nice blue actinic lighting to make your corals color pop but you will have the lighting to get them growing.

What is eating my corals?

what kind of snails do you have? if you do not have enough food in your tank for the snails some snails will start eating your corals. for example i know the bumble bee snail and the nassarius. i seen a lot of videos on youtube of nassarius snail eating corals. and my lfs said that bumble bee snails are not good with hard corals. make sure you have enough food for your snails. and to me it sounds like you have a feather duster growing from your live rock. feather duster are harmless they wo not do nothing to your corals
