    Hi guys,
    I recently bought a 17L tank and was told I can fit four goldfish in it (my goldfish are each around 2cm and seem perfectly healthy and happy in this bowl). However after researching on the Internet everyone is telling me I need at least 40L per goldfish, on top of the 30L to start!!

    Is this accurate? If so, will my fish survive in a 17L tank?

    It's a good thing you didn't ask this on an Aquarium forum or even in the comments section under a goldfish video on YouTube; proud fish keepers would go mental over this.

    I'm not going to go mental though. I'm nice.

    When we first go to buy goldfish, they will be young and tiny. Like a porn star (I don't know why I just compared goldfish to porn stars). A 20L tank would be alright for the fish when they are young, but they can and most likely will grow many times larger than their original size. This is why so much water is needed; their growth and pooing potential can make it difficult to maintain good water quality even with regular cleaning and good filtering. Overfeeding is one of two common causes of goldfish death; bad water quality is the other. Goldfish really are much better off in ponds for these reasons.

    They will survive, but probably not as long as they could/should. It might not take long for them to gain a few inches. Apart from that though, have you got any filtration in your tank, etc?

    I appreciate the advice I had always heard that goldfish grow to the size of the bowl, but from what I've read online this isn't the case!

    Yes I do have a filter in my tank and I've been having the water checked weekly - as of yet there hasn't been a thing wrong with it. I'll continue having it checked for the next month or so to monitor ammonium levels now that the fish are in there.

    Just feel gutted that the tank is too small - why allow me to buy four goldfish if they know the tank is too small??
