I have a 15 gallon tank with a 5 gallon sump and I am currently stocking a 8" green LTA with a 3" true perc hosting it. I am thinking of adding a jawfish and also a fish that would be considered a fish that swims in the water column. What is a good small fish that is reef safe and stays in the water column more often than the rock work? I was thinking a cardinal but maby they might get to big for a 15g.
PS the tank is a 20g regular with the back 5g being the sump.
thanks
