Recently, my Yamatos have been doing the kamikaze by jumping out of their tanks. I have seen them out of the tank on several occasions. I suspect there is something wrong with the water quality, hence the strange behaviour, so looked around the tank and found a dead fish trap on the filter. This might have skyrocketed the ammonia level and made the shrimps unhappy? Anybody experienced their shrimp boycotting by jumping out of their tank?
