Ds would like a fish and I've said yes but want to get him something low maintenance (they're all fairly low maintenance aren't they?) so have questions:
What fish should we get?
Should we get 2?
Will it definitely need a heated tank?
Will it be hard to keep it alive?
I just told him that it's his responsibility to look after it and he looked quite worried as I'd just told him about my goldfish dying (I was 25, didn't know what I was doing, won it at a fair IIRC). All and any advice welcome. TIA
