Odd convict behavior

[Lippy]

I have a 2-3 year old convict that has been acting funny for the past couple of weeks. He has been swimming in the the top corner of the tank mostly straight up and down. Still eating, but wont move from that corner. Anyone?

I could be wrong, but doesn't look like a convict to me, but that's not what you asked, sorry. Have you checked your water parameters. I've read this could be a response to something going wrong with the water

I have checked the parameters, the are normal. All the other fish in the tank are healthy too. I was thinking the othe fish were bullying this one, but no sign of that either.

hmmm add any new fish lately, tank size and stock?

 

[Lippy]

No new fish in this 55. The tank is a little over populated I think about 20-25 good size fish. but very well filtered.

I guesd that could be it then.. he's crowded?
