Suddenly lethargic Antenna/ Suckermouth catfish
I've got a 31,7 gallon tank in which about 35 fishes live.
For cleaner fishes it is: 2 Antenna catfish (black and brown) and since almost 4 weeks now also 5
armored catfish (others are all non cleaner fish).
While 1 antenna catfish was lazy to start with the other (black) was always very very (hyper)active.
Moving along the glass window constantly and cleaning / eating. Also he was within minutes on a
fodder tablet when it was thrown in.
A good week ago his behaviour changed almost over night. He is almost constantly only at 1 location
and ignores the fodder tablets completely. He still changes places on the glass, but not constantly like before
but more like 1-3 times per day in total.
Other things I noticed
The fish is under 1 year in age. He is in the tank since 2-3 months.
If a fish gets too near and tries to bite him...he reacts as aggresively as in the past
When he moves a bit along the glass I do not notice any lack of strength with him holding onto the glass (thus as strong as always)
There is nothing on his body that seems like it changed (no inflated stomach or visible fungus, ...)
There was a problem with the filter 4 weeks ago which quite a few fishes their lives (I overlooked that I had to remove the filter compltely to see if it is too dirty to work any longer....lesson learnt even if it was a very sad one back then).
Aside from that and one homicidal fish in the tank there is nothing that seems to have changed or is out of order.
Fishes are fed with the tablets and flake lining (same as since months).
As I know from past experiences a sudden behvaioural change is almost never a good sign I'm quite a bit distressed
there, but at a loos as to what to do (or if I'm overreacting and that change is normal).
So the question is: Is there anything I can do there or look out for?
