I am not going to move the male out of the tank as nobody is picking on my female. With being away a bit however I did want to make sure that if my henlei has her pups while I am away that I minimize the loss of pups. I have designed this out of egg crate, 1 inch pvc, zip ties and slate to weight the thing down. This way none of the current rays can get under it to hurt the babies and I dont have to worry as much about being away. The first run did not work as my large female tore the damn thing up, but I have improved it now with more weight and 22 suction cups stuck to the bottom of the tank. 22 may sound a bit excess but when you have a 40 or 50 pound piece of muscle tearing at everything...she does not want in the tank it is better safe than sorry.
Would something like this work?
