My 2 tinc cobalts are always jumping and hitting their heads on the top of the glass like they are trying to get out. They are always climbing the glass and also trying to dig their heads where the glass and soil meets. Is there something wrong with my tank? It is a 15 gallon, heavily planted so there is a lot of hiding places and i mist the tank 3 times a day so it is always pretty wet. Is it possibly to humid and wet? Since it has gotten warmer the tank is usually around 83-86 degrees daytime and 80-83 nighttime. my one tinc has rubbed the color off its nose from trying to "dig" so much. Is this just their behavior or am I doing something wrong?
