I have kept 2 fuzzy dwarf lions in same tank for 2 years. They were amazing little guys and I found them to be like little puppies of the sea!! And they can warm up and get friendly to ppl.. so be careful!!

I also had a 55g and I kept them with (plz don't yell at me lol) a foxface and a blue indigo hamlet. This was all before I found this site lol Anyways.. I never had any problems and everyone got along! If I tried.. I would've been able to feed the fuzzies right outta my hand! I miss them

I lost one to an emerald crab and the other in my devastating tank crash! Ugh.. So.. I think personally you would really enjoy the fuzzies compared to the volitans
Edit:
I would also like to add that fuzzies are hilarious to watch while feeding and they like to beg! Its amazing how big they can open their mouths. If you do decide to go with fuzzies.. I would recommend you try to get them already feeding on frozen foods, as fuzzies can be hard to switch from live to frozen

It took me more than a year to get them to eat ANYTHING frozen..
BTW..

WELCOME TO RC!!
