    Default Discus jumping out

    I have not had Discus in a while, but recently my Discus seem to get frightened for no reason. Unless they are seeing shadows that spook them. I do a 50% water change every week in a 185g. The fish seem fine and healthy and eat and beg for food. I can just be sitting watching T.V.and I will hear splashing and a Discus rapidly swimming around in the aquarium and sometimes just in circles. They have even damaged themselves ramming in to the glass or driftwood. Then for weeks no issues. I do have a wooden top covering the aquarium except for a 6 in. space in the back. Over the last 6 months I have found 4 Discus had jumped out. I have started adding floating plants to cover the top to see if this helps. Anyone have any clue as to what could be making them do this? I will be adding glass tops. Well established tank temp. 82, 0 nitrates, o ammonia. I do have 6 Rose Lined Sharks, 1 Cardinal Tetra, a few Bristlenosed Plecos, and a group of Assassin Snails that must be spawning. My MTS are just about all gone.

    Where is the tank located and the how high off the floor the tank is? Also can you provide the type of water they are in(Tap,RO, RO mix,pH and hardness)?

    A few things jump out to me... One... and always one... water changes... Once a week just never seems to cut it for discus and I would try my best to up that if you can... Or up the % for that one weeker, but ideally you should be doing 2-3... I get your test results seem fine but still, thats always the go to and a change in water params could cause this...

    Second are the sharks... Those roselines are fast moving and non-stop swimmers... If the discus are resting or trying to and that school comes darting by, it is going to spook them and they will def dart and cause issues...

    You can try egg crate or mesh over that opening... Seems if there is a spot they will find it... Even with glass tops, that space between the HOB if you have one I have heard of people loosing fish that way...

    I had similar experience. It coincided with some road work including water line work on my street. Had to use RO water for a few weeks, which solved the problem. when the road work was done the problem with my tap water disappeared.

    I was doing a 75% water change and that seemed to trigger them so that is why I cut back. I use tap water. Same water I used when I had Discus before. They and my Angels spawned all the time. It is near a window, but there are curtains. I thought about the Roseline Sharks, but they don't really get close to each other. I did have some Odessa Barbs that I moved out thinking they might be nipping at them. I have been able to watch them just take off for no reason. No other fish are around them. After it is over they will go sit behind a piece of slate for a couple of hours then come out.

    Few years I had tank not far from the window with curtains and still found that my Discus were skittish by shadows casted every time a bird flew by or wind shaking the tree branches I lined the window with automobile window-tinting material which made the room darker. That stopped the Discus from sudden darting.

    In any event, tanks need to be covered. Discus can and do jump out of their tanks.

    I was having a conversation with a local Discus keeper and was surprised when she mentioned she had had one jump out of the tank - Last time that happened to me was probably 30 years ago and happened in the middle of the night.

    Last time I saw some jumpers were at a discus breeders garage, as soon as the electric garage open the Discus started to jump right out of the tanks,
    the keeper took off his hat to catch the flying Discus.

    Beware of Flying Discus!

    I've repeated this story a few times but after looking for one of my Wilds, w/o any luck, I looked down to see that it had jumped in the middle of the night into a 5 gal. bucket of RO water that happened to be standing next to the tank, and the water was fairly warm as it was summer.

    No problem and the fish was placed back into the mother ship.
