Thanks for all comments every one... As far as the fronts go... its a sad story... There WAS one spot near the bio wheel filter that I didn't think was any concern but, the male found his way to the floor one night. After that, the two females starting fighting with each other. Before I could get them separated one passed on... Then the queens started ganging up on the last one... so I put her in the 90g w/the vieja bifasciata(the tank is divided). She was fine for quit some time, but she got ill. I think it was from the feeders. Needless to say I don't buy feeders any more... The only fish they get these days are the ones I collect from shucking scallops.
