Can I add these to my tank?


I have a 120 gal tank. I have a 6-7 inch lion fish, a 3 in niger trigger, yellow tang and an eel.
Can I add Crabs or horseshoe crabs? My kids love them. I do have 3 hermit crabs in the tank now, but for how long who knows. If I can't get crabs any suggestions what I could put in the tank to help with future algae?
Also any suggestions on other cool fish. I am thinking of a puffer....
I am using a sump, protein skimmer and a fluval 404. I am also using a coral life pro lighting system
Thanks for any advice,

Mostly you'll just have to use your hand and a scraper.
Other tang or herbivore will help with algea on rocks.


Do nigers eat all crustacians? If I were to by 50 crabs.....whould they be all eaten? I need algae relief


How about this package. Is this appetizers for a small niger?
