I have 6 green dwarf pikes in a 90 gallon tank and was wondering if anybody new how fast they grow? I have had them for about 5 months and they haven't really grown at all. Are they slow growing? I am thinking they were stunted when I bought them at the lfs. You can usually tell by how big their eyes are compared to the body and mine look okay so far. They are about 2 inches from end to end.
