My dd had 6 white cloud mountain minnows in a 60 litre tank in her room but she has lost interest in them and I am the only one that feeds them, checks on them, watches them. So I'm thinking I might make the tank more interesting, put something in I like as well. There's no heater in at the moment but I have one I can put in. How best do I increase the temperature, just at the speed the heater heats it or more gradually?
There are only 4 minnows left, what can I add to live with them? Could I add in maybe 6 small tetras of some sort or would that be too much?
This all depends on me finding somewhere to put the tank in the living room...
