Protein Skimmer without Sump

A newbie here. Setting up a FOWLR tank in my old 65 gallon tank. No sump and the tank has something that makes it difficult to put anything HOB. Will probably add a sump in the future. Since they're expensive and most recommend in-sump models, I would like to ask what problems there are if I put an in-sump protein skimmer in the display tank aside from it not looking good, assuming I put it at its recommended water level. Do most in-sump skimmers have sufficient inlet cover to not suck fish in? Or are bubbles going to be too numerous in the display tank that might affect the well-being of the fish there or is it just an aesthetic problem? Am thinking of getting a Bubble Magus Curve 5 skimmer.
 
You will need to add some type of inlet screen to prevent livestock from being sucked into the pump. I think the micro bubbles will become problematic at least on occasion. Do you have room for a hang on the back skimmer?
 
I would either wait until you do have a sump or just manage without. A 65g FOWLR can be easily managed without a skimmer. I ran my 60g cube reef tank without for all of it's 22 years. Just keep up on water changes and you'll be fine.
 
if I remember correctly, I had a HOB reef octopus that I hung from the rim so it was actually in the tank and it worked that way. It looked a bit ridiculous but it made do until I learned about HOB overflows and used one to add a sump.
 
Tunze DOC Comline skimmers are what you want IMO good reviews and designed for in-tank use, although any non HOB solution is going to require you to maintain water levels in the display to a degree; an ATO for evaporation is avised alongside it if not already in-place.

There is a DC version for 50 more too. This skimmer should have no problem adapting to a sump in the future if you get one, or any tank honestly, they are just not particularly big (although there is a larger one for 300).
