Cool Cory Catfish acting strange....

Hey All,

I've had my 55G up and running for over a month now. Everything is perfect in the tank. Levels are all where they should be, all the fish are shoaling beautifully and everybody seems happy. Except for one of my cory catfish seems to want to be a middle tank dweller....

Yesterday afternoon I noticed he was sort of hovering in the middle of my tank, right in the center of the glass in the front....just sort of levitating. I have seeen catfish do this before, where they sort of hang out with their mouth suctioned to the glass, but I have never seen my catfish do this before. Is this just a new trait of one of my catfish or should there be cause for concern?

Thanks for you help!

Johnny

If water parameters are in order,, Zero ammonia,Zero nitrites,and nitrates twenty or below,I would not worry. Corys are funny little fish who in a healthy tank,, will explore all regions . I have not seen many that did well in the longterm with temps much above 78 degrees. They do appreciate their shrimp pellets along with other foods they scavenge ,and also like algae wafers occasionally. Blood worms are also greedily accepted.

The most important medication in your fish medicine cabinet is.. Clean water.

I concur fully with 1077. One other odd thing about corys, sometimes one will "faint" for no apparent reason. It just flops over on its side, sometimes on its back, looking dead except it will be respirating. A few moments later, back to normal. I recall reading about this a while back in a magazine, but can't remember much except it is "normal" although infrequent and not a cause for concern.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If youíre going to take it under your wing then youíre responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

ok, yep, I just tested the water again and the parameters are fine. maybe I'll pick up some blood worms for the little guys to munch on.

thanks for the help

My cories swim up top with the danios alot. They play in one big group. At first I was a little surprised because I thought they stayed at the bottom but no so, they are as energetic as the danios sometimes it looks like one big party. Unless it starts looking sick and you water is good, I wouldnt worry about it.
