I'm a complete novice and any advice is very welcome.
Well, since you are open to advice, here are some thoughts as I read through your post:
180 litre is approximately 46-48 US gallons, correct? What are the dimensions of the tank (length is going to play into some of the feedback regarding the species in question)?
What are the parameters of your water?
what specific rainbow fish have you got - they can vary in size, etc and that will play into recommendations made.
the clown loach - he needs to be in a group of six or more and, given their potential size at maturity, if you keep him and obtain the friends he needs, a larger tank is in order
The red tailed shark - another fish who will ultimately require more space than is available in the current tank
Ultimately - I would suggest taking a moment and looking up to the top where the "tropical fish profiles" are linked - there you can read up on each species and see who might fit best with who and in what tank. At the moment, though, the fish you have are not suited to the tank/community you have for various reasons.
You mentioned having multiple tanks - what other size tanks do you have (looking to be able to offer possible combinations that could be moved into various tanks that you might already have available)
