Protein Skimmer for 20g long

Hey Guys, so I have posted this question before but did not get many replies, which means I did not get the info that I need.



I need to know a good protein skimmer for my 20 gallon long which will have 2 ocellaris clownfish and 2 camel shrimp 22 pounds live rock and 16 pounds live sand in it, and maybe a little more but nothing large enough to note. I will not have a sump or anything like that so I just want to know if there are any good HOB skimmers or in tank skimmers, I would prefer HOB because of the limited space in the tank.



Thanks so much!
