I have a IM 50 Fusion Lagoon which is 29"L x 19"W x 16"H and i have the returns and 2 6015 Tunze powerheads (475 GPH) at either ends of the tank.
Right now all I have in the tank is a watchman goby + Tiger Shrimp and a Midas Blenny. I plan on getting a Royal Gramma and a few other fish on the smaller side maybe 2-4" max. I notice my Blenny always stays on one side of the tank and keeps from getting directly in the path of the powerhead. Could the flow be too much? In this size of a tank with smaller fish with my flow be too much for them?
