Clean Up crew for aggressive tank

[nw2sltfsh]

Hi everyone -
I am relatively new to this hobby and have a 110 gallon tank set up now for a while. The tank is turning aggressive based on the fish choices that are catching my eye.
What I need to know is what is the best cleaning crew to get for an aggressive tank?
The occupants of the tank at present are:
a Juvenile Huma Huma
a Juvenile Bursa
a Juvenile Niger
a Juvenile Porcupine Puffer
Over the past month I have driven to over 20 LFS in MA and RI looking for some input and keep getting told all of the choices would become dinner -
Please Help!

You most likely will not be able to have type of clean up crew.
I had astrea snails for awhile with my puffers and they lasted a long time. But I think this was a freaky exception.
Sorry.

The Puffer is your problem, lose him and you can have a cleanup crew. Keep him and your cleanup crew becomes an expensive lunch.

my hummu loves snails i got the monster big turbos and he had a rough time getting them off the glass he really doesn't mess with the hermits or my starfish or the emaralds so i would just try to keep something and see how they react to them

Imo, the best clean up crew for an agressive setup is a uv sterilizer.

thank you all for the comments and suggestions - I was doing some reading and saw a comment about a diamond Goby as a good option
I think the advise here is great and appriciate a place to go that doesnt involve going to my LFS 0- while those guys are great i seem to always buy something for one pet or another if I go in there -

Thanks again for helping a newbie and being pleasant - I was honestly afraid to post on this site after reading some of the replies people get
