Thank you for the welcoming and the helpful advice. I will keep an eye on these Asterinas. If they become a problem I will remove them or introduce some Gnathophyllum elegans or G. americanum. The bristleworm ist now removed into the tank. Thanks for the warning, though I didn't felt the need to pet this little friend. Here's another picture of the mushroom-looking animal. I will try to make a better one, if they've opened completely. It's very interesting to see what comes out of the live rocks. Nice to hear, that the unknown animals are not harmful and that I could go ahead accordingly to my plan. But I have a question about the Clown Gobies. A friend, who has much of experience in this hobby, told me that the Clown Gobies are really aggressive against other members of the same species. He recommended me a pair of Amblygobius rainfordi instead, wich are also nice looking and interesting fish. Nevertheless I really would prefer a pair of those Green Gobies. Do you have the same opinion like my friend or has anyone of you already kept a pair of these Gobies in a Nano tank? If there are any doubts about the compatibility of Gobies I would rather choose another species. @ Doug: Thanks for the invitation, but I'm from Germany as I wrote. So, it may be nice to join the meeting, but I have to find a financial sponsor first. Kumonryu

Hello, to discuss information about this interesting hobby and to practice my English I joined this forum. After years of keeping and breeding freshwater fish I got my first Reef tank, an 8 gallon (30 litres) Nano Reef, wich was running for about half a year at the former owner. It contains a skimmer, two pumps, lighting and some livestock, like Sarcophyton, Xenia, some other Soft Corals, Asterina starfishes, brittle stars, snails, Caulerpa and Red Algae. Aside from that there are some animals wich I was not able to classify. So I may need some help from the experts of this board. At first there are some animals, on wich I'm not shure if they are just Mushrooms or harmful like Anemonia cf. manjano. Here is one of these animals beside an Asterina Starfish: And some other between the Zoanthids: Also I have no idea what this small yellow thing may be: There are some of this small snails, wich I could not identify... ...just like this really small animal: Last but not least, I'm not shure if this is a Fire Worm or just a ordinary and harmless Bobbit Worm: For now I will wait a few weeks. If the water parametres are allright some more animals will move into the tank. I like to introduce - some other (eventually more colourful) Soft Corals - a second (and slower growing) species of Mushrooms - Gorgonia - two or three Clibanarius tricolor - a small group of Sexy Shrimps (Thor amboinensis) - and a pair of Green Clown Gobies (Gobiodon histrio) Does anyone have objections to this plan? Well, at last I have to apologize for my bad English. I'm from Germany. Greetings Kumonryu
