Hi I've got a 4 year old Plec in a 60 litre tank.
I change the water every couple of weeks and I add the water treatment to counter the chlorine in the water. I haven't added any new fish to the tank.
Over the past few weeks, my fish's poo's havent been dark and solid like usual, but clear in colour, and he is now lying either on his side or upside down on the bottom of the tank.
I've bought some treatment for bladder problems as he is unable to keep his balance, but this hasn't helped him.
he has been lying on his side/back for 3 days now, and isn't eating or pooing at the moment.
Any help appreciated.
Jon
