How I found it: while non-photosynthetic corals web search leads mainly to general information and don't do it, the search for Menella and skimmer - gave that (through the illustrated croatian forum, which I don't understand). And Scleronephthya plus skimmer search - non-photosynthetic forum at Ultimate Reef (uk). You never know
The Karl's tank is interesting for me by aquascaping, possibility to have a lot of LR, even with high levels of feeding (my rock accumulated nitrates and phosphates with time, so I moved it after mechanical filtration). Also - classification of tube anemones and their keeping. I have one, and hoping to have more, if they will be compatible.
Translation: Google has Language tools (at the right from the search box), pasting url do not working for the frames, so I copied pieces of text for translation box.
Was particularly impressed by automatic translation from Japanese - the best looking tank with Dendronephthya, you know it:
Japanese site and
link to it from RC.
