Advice for my tank

[ArchXIII]

So, currently my tank is 6 months old. 55 gallon FOWLR, it's current inhabitants are

Two clowns, Tailspot Blenny, Banggai Cardinal, tomini tang (I do know I'm going to get told to move it, like the rest of my fish she is still young and not fully grown, when we move the misses has agreed to let me upgrade my tank), a chocolate chip starfish, and some snails.

My main question I wanted to ask is, I have a fake, hollow, rock structure that all five of my fish love (clowns sleep there, blenny sleeps there, cardinal sleeps behind it, and sometimes my tomini sleeps in it, although she also has a hiding spot within the actual love rock), and while all my fish are juviniles and act fine around it currently, and I actually do like the look of it, I'm afraid when they get a bit bigger there may be some aggression (main thing that made me think of this is that my Clowns recently had a marital dispute, they're fine now though). The reason I'm anxious to remove it however, is that I don't want to stress them out by taking out one thing they all use and feel comfortable with, and wanted some opinions on if I should or not.

Also I recently went to upgrade from my hydor skimmer that sits inside the tank (regret that purchase), and put in a seaclone 100 (I know it's not the best, but it's better, at least, and since my work actually carries it, I got it for super cheap. However, when I had put it in it released lots of microbubbles continously, and I was worried about it being bad for my fish. Will it harm them to let it break in inside the tank? Also, how likely is a HOB skimmer to leak? I'm overly paranoid about that as well.

And last but not least, AqAdvisor said my tank is not overstocked, but how stocked is it?

(Picture is a few months old, as I don't have a more recent full tank shot, and my lights are off).

Get a second one so there will be no more bickering.

Will it harm them to let it break in inside the tank? No it will not harm the fish. Make sure your cup is on tight, this is a known cause of the bubbles. You can search the internet on this issue and fixes.
Also, how likely is a HOB skimmer to leak? I'm overly paranoid about that as well. Not likely unless you damage it or dont clamp the hoses securely.
And last but not least, AqAdvisor said my tank is not overstocked, but how stocked is it? Its perfectly stocked.

Sure, you could get more fish or have less. The balance will be; how many and how big when they grow, aggression between fish, amount of hiding / safe places they have to go . More fish = more stress = more prone to get diseases.

Fish disputes r common, as they grow older the pecking order will constantly be challenged. They will usually work it out in the end. As far as more fish, just remember that the fish grow, and as they grow they need more space. Just use common sense when adding fish, look at their movements, habits, and such.

I have 13 fish in my 75 gallon but 5 of them are smaller..green and yellow clown goby, firefish, damsel and royal gamma basslet,.so it is not so much how many, but the size. For me I would rather have many small fish than a few big ones.

I did end up going to my Lfs the other day, and after talking to the guy that manages the fish and tanks, ended up getting a solon fairy wrasse. Since my parameters are still good, and him and another heavily experienced employee said one or two more would be fine (this is my absolute last fish until I upgrade however). My tomini hasn't been the biggest fan of him, but if I leave only the blues on she seems to ignore him, so I may leave it like that for the next few days so they can get acquainted better (my other fish don't care that he's in there). I do also have my tank covered so my new guy can't jump.

I have been wanting more live rock anyways, so I'll be placing an order for more reef saver.

I also would like a sump.. I currently have a 20 gallon fresh water that I'd like to tear down, and turn into a sump. However.. I can't place it underneath my aquarium where we're currently at. How easy would it be to hook into my tank, if my sump were to stay on my 20 gallons current stand? It's currently maybe 5 feet away from my FOWLR. Give or take a foot.
