Just to be a party pooper - the animal cruelty really disturbs me :( I wouldn't put an ant in that small a tank, much less two Fantail goldfish. Horrible. Even worse in the series "Hormones" where Phu gives Toei the Pygmy Hedgehog which lives in a cage that's properly sized for a transport box... When I had a Pygmy Hedgehog, his cage was as large as about 1/2 of a normal sized single bed or slightly larger... and that felt a bit too small
