Without wanting to sound rude, your friend's goldies may 'seem' happy but stunting is a huge reality for goldfish in tanks that are too small and I would never suggest stocking them in a biorb at allI recommend the standard minimum 20 gallons for the first goldie and a further 10 gallons minimum for each extra fish. I'll be adding another tank to this thread soon - a big 40 gallon tank for some orandas and a black moor

No you are not being rude at all. I value your opinion greatly.

In retrospect I should have said it's not the best practice. My friend has a 60L with one fantail and three small goldies. I'll have a subtle chat about moving the extra ones. It's very difficult because as we both know there are fish keepers and careful owners of fish and the former is probably what they fall under.

Have you used the same username on the forum you speak of? If so I'll chivvy it up as I'm a moderator there!
I modified the biorb so I can return it to normal if I want. I took the filter section out that holds the sponge and bubble tube, tied a knot in the end of the airhose and added a second one way valve to the tube to save any leaking.
I then filled the filter basket bit with pebbles then added my well washed sand and an Ehiem Aquaball filter (not the smallest one) so that the outflow can be directed to the surface for extra agitation.
It's as simple as that
