It works great just remember tinfoils grow fast and do better in groups of 5 or more some will say less in the shoal works best with 5
Tinfoils are great cleaner fish they even eat my rays crap
I have a shoal of 10x 12inch tinfoils with a mix of 5 gold and 5 red tails
No problems with the tigers at all
Go for it just remember the size of them in a 5x2 mine were about 5inch when I got them about 15 months ago now they are 12 inch but the red tails grow slower and stay a bit small as my gold ones are much bulkier and deeper body
ook just bought 2 barbs, they had two xl barbs, 12$ each haha, will post up pictures, i originally wanted 3..they are good size too about 10" i hope they all get along
