Unfortunately, my seahorse died last night, leaving me with one pair of sunbursts remaining. The water parameters in my tank are all good (ammonia zer0, nitrates 0-10) except the PH is a little low (8.0). I will be remedying that over the next few days. My tank is a 35 gallon hex, 25 inches tall. Not quite the 30 inches you recommend.
You mentioned stress as a cause of disease. My smaller male was frequently hooking onto to the dead ones tail and dragging him around over the past month or 2 and he didn’t seem to like it. Could this have caused undo stress? Is this normal behavior when more than one male are in the tank? Also the dead one was one of those that used to go up and down frequently in the tank and even curl up into a circle at times while doing it. It seemed as though he was OK otherwise. None of the others did this. Is that unusual behavior? Just trying to figure out possible causes or abnormal behavior traits so I can try and prevent re-occurence in the future.
Again thanks for all your help and advice.
