No problem in asking. It's sad to see stressed/ transparent nems, the recuperation is possible in some cases but it takes months or years of dedication. You need some months to:
Get to know all equipments, experience the first failures;
Pass thru algae phases, some may last a long time;
Reach quimical and biological stability;
Drastically reduce time your hands are inside changing things;
Fight the first pests;
Work on the most important mods;
Have enough time to observe if all is well;
Learn how to handle invertebrates, acclimatize, feed, etc;
Get confidence you will not kill the animal but give it ideal conditions.
By this time you should have enough knowledge to keep a more sensitive animal. Nems walk, stay where they want and may burn other inverts. You need to keep an eye on it for some time. At last... There are no guarantees the clownfishes will eventually notice it.
