Thanks friends, for the advice infact i had two and the other one died on the first year that i owned it, his tank is on the floor so it has the lowest temperature from the whole fishroom but you know it's still around 30 degrees. Because the room is upstairs, my hope is that i will do a pond so hopefully for next summer i can put it in it.
Can i ask if it appriciate the currents in the water or not please? it looks doing very well with the oddballs in his tank and most of the time it looks playing around but i'm not sure about if it's ok for it, there is a bit of strong current in the tank.
