Tropical vs Coldwater

Which is the easiest to take care of? I have given the tank back to its owner, but am going to get another tank and some more fish. Thing is I dont know whether to stay with the goldies - my two are just lovely - or whether to be a traitor and go warm. Is there any difference in taking care of the two lots of fish and which is the most straightforward to look after?

Also, did anyone see on the news the other night of the fella who had trained his goldfish to do all sorts of tricks - go under a limbo pole, play netball, and loads of othet things too?

I dont think there's much difference really, apart from having to warm the water. Trops or coldwater, they both need to be kept clean, gravel vac'd, fed etc.

In some ways I find the goldies easier - dont have to bother too much about water temp, in other ways harder - algae problems.

Hard to choose betwen them really.

I did see the thing about the fish doing the tricks, it was great :lol:

I agree with Diana. Both require an equal amount of weekly care and tank maintenance. The only thing I would say is that I worry less about the coldwater tank if I'm away because (a) there's no heater to malfunction and accidentally boil/freeze your fish and (b) if the filter was to break down for any reason, the goldfish would tolerate increased ammonia and/or nitrite levels longer than the tropicals would.
