i am planning to add a small endlicheri to a 125 gallon with a 5'' spotted gar. the endlicheri stocks at the LFS are usually 2'' to 3''. i am afraid that the gar would attempt to predate upon it. the gar grows considerably each time he is fed so i was wondering how long he can go without food to temporarily slow down his growth, or would doing so cause him stress and stunt it's growth?
