Came onto the previous thread just before it closed, but echoing what others have already said. That fish tank is cruel. I have a 40 litre one which isn't considered a particularly large tank and have no more than 10 fish in it. 6 of those are tetras which are tiny, a siamese fighter, a clown loach, a platy and a cleaner fish.
The tanks take a lot more looking after than Hinch is ever going to do, testing the water, doing a part water change etc.
I can't see her putting her hand into the tank, taking out the filter and cleaning the fish poo off it.
