I have got two Hydrolycus scomberoides and one Hydrolycus tatauaia. I'm eventually going to put together a school of three H. scomberoides and two H. tatauaia. The growth is slow and steady for these fish. They are currently in a 75 gallon tall grow out tanks with a buffer school of silver dollars and are going to be moved into a 360 gallon when they are over 7-8 inches. The Hydrolycus tatauaia are the most aggressive out of the two species. Some clearer pictures tomorrow.
