A heater for 60 litre tank

[ReallyTired]

Can you recommend me a new heater for a 60 litre tank. I have some 2 yatimoto shrimps at the moment and I would like to get a couple of platys, mollies and guppies in the future

You mean the size or the brand? I've always just bought cheapo ones. Unless your room is super-cold then 50 watts is enough.

60 litres is a bit on the small side for mollies and platys but you could have a little gang of guppies in there, no problem.

Thanks. I meant the size of heater. I did have a whole gang of guppies, but they died of cold as I didn't realise the heater had packed up.
I just have two very hardly yamato shrimps left who seem to be as tough as old boots. How long do you think I should wait before getting new fish?

I might be getting mixed up with guppy threads. When did they die? Was there any illness?
