Biorbs are bad for goldfish II

First, if you are keeping goldfish in your Biorb, only keep goldfish in there. If you have central heating you don't need a heater in your Biorb. Goldfish are happy in cold water between 15-20 C. If your house does go below that then put a Biorb heater in there, but set the temperature to come on at 16 C.

Before you buy your fish you should set up your Biorb and let it run for a couple of days. Make sure all the chlorine is gone. Then buy only 1 fish first. Add some StressZyme (or other bacteria liquid) after you've added the fish. Change water if needed - see what your water condition is like, if getting poorer then more often up to daily - usually with 1 fish should be fine. This is so the bacteria can start growing. Wait 1 week do a partial water change, then add another fish. Monitor water, partial change if needed then add another fish after a week.

I think 3 is enough - they will grow faster with more space, and you'll be happier too if your fish are healthy. :) You might be able to fit 5 in there if they are small and you have a 60L but they won't be small for much longer. If you have more fish you will have to change water more often, and you will have to move to a larger aquarium more quickly as they grow larger. When mine were just 1.5inches each I only had to change once a week. Now that they've grown to 2.5inches sometimes I have to change twice a week. When they get to 3inches I will have to change to the 60L or a proper aquarium otherwise the daily water changes will be too much for me. Luckily fancy goldfish usually grow only to about 4 inches not counting tails. Goldfish can live for over 40 years! So 3 is a good start, see how you get on with that.

With the celestial bubble eye, they will have trouble feeding if you keep them with fish other than telescope eyes and moors. Other goldfish will have much better eyesight so will eat all the food and you'll find your bubble eye starving away to nothing your eyes. If you have other fancy goldfish, oranda, ranchu etc you can't keep the bubble-eye. The moor and telescope eyes are ok - but you will need to use the ramekin/plate trick otherwise your telescope eye will also starve (due to its eyesight being poorer) if kept with other fancy goldfish like ranchus and orandas.

Another thing with the celestial bubble eyes is that Biorb has this tube sticking out with edges. They might break their bubbles on that, so you will have to make sure the edges are protected, and there are no other sharp things in there. Bubble eyes are not a good choice if you are a beginner with goldfishes. Orandas, telescope eyes/moors are much better.

Also, don't keep fancy goldfish with the other goldfishes like sarasa comets that can live in the pond outside. The sarasas are much faster and will eat all the food. Starting to see a pattern here.... :) And they might think your fancies are pregnant (due to the round tummies) and chase them.

Finally only feed them once or max twice a day. And only as much food volume per goldfish as their eye size (normal eyes not telescope eyes). They might eat from your hand if you train them, and that will also be a good way of making sure they all get to eat something.
