In my 180 i have a colony of 7 moba fronts with a few sevs and geos. Within the last 3 weeks ive found 3 fronts behind the tank that have jumped out. Water quality is fine temp is about 80degrees filtration is 2 fx5 and 3 aquaclear 110's. I also have glass canopies with the only opening where the tubes from the filters go into the tank about an inch. Entire stock is 6-8inches and healthy. I cant figure out why or even how these fronts are commiting suicide. Any help would be appreciated. Ive noticed no aggression or mating behaviors
