yeah, I guess its a sacrifice. I have been keeping fish for almost 20 years now (I am only 31 lol) and I have had tinfoils almost all the time. but I have never had more than 2 in one tank.
 
in the past, I have been able to keep many other fish with a set of 2 barbs without major feeding issues.
 
but with 5, its a different story. I raise the tank lid, put the food in. by the time I have walked over to my shelf to put the food can down and put the lid on most of it is gone when I walk back over to the tank LOL.
 
and I feed them a fair bit.
 
but its a sacrifice.
 
having 5  barbs in a proper school like this looks stunning in the tank.
