compatible fish with all varieties of goldfish?

I would not add cichlids to a goldfish tank...

With a 113 gallon tank you can have about 2-3 single tailed goldfish and maximum 8-9 adult fancy goldfish (if they're full grown though, I would try to allow each goldfish at least 15-20 gallons each). If you're going to add tank mates, I would only get about 6-7 fancies.

The only tank mates that are known to get along with goldfish are Bristle/busy nose plecos, rubbernose plecos, (common plecos get too big and are known for sucking onto goldfish) weather loaches, white cloud minnnows, and maybe danios. Try to stick with fish that thrive in colder temps.

I would be a bit hesitant to get the smaller fish as goldfish like to eat whatever they can fit inside their mouths.

How could anybody propose extra fish? No fish compatible with goldfish stays little besides for the white cloud minnow, and so they may be swallowed. The opposite fish compatible develop over one foot lengthy. Your tank is severely overstocked. For what you've now you want at least a 95 gallon tank. Including extra fish to an already overstocked tank is just not a excellent proposal. You would supply the usual goldfish to a pond, and buy at least a forty gallon tank for the three fancy goldfish.

Possibly the white cloud mountain minnow would work.

But it is important to remember that even different goldfish are not very compatible with each other. The veil and fantail types might not get on with the ordinary sort. White ones get picked on sometimes. Large ones will chase the smaller ones to exhaustion.

Other fish that might work would be zebra danios. Both the minnows and the danios need to be kept in groups of at least six. Even though they are small fish, they need a lot of swim room. The goldies also prefer to be kept in groups of like-types - at least 4 is ideal.

The tank is best if it has a lot of surface area. Your tank sounds great. With high filtration and some plantings, it could handle a dozen goldies or fewer if you add tank mates.

Goldfish should be kept in species tanks, not with other species of fish at all. They should also only be mixed with other Goldfish with similar traits i.e. commons with comets, bubble eyes with black moors. If you mix a long-bodied common with a black moor, the poor disabled moor will be bullied and killed by the larger common.

Comets/Commons are huge growing pond fish, a 113g gallon could only house two, maybe three at a push with massive filtration.

Fancies need a minimum of 30g for the first fish, 15g per fish thereafter. You could house 6-7 absolute maximum fancies in there, less for larger fancies like Orandas who get really big.

If you want a community in there, don't get Goldfish.

Hey Benin congratulations for getting that enormous fish tank! I would suggest you to not mix any tropical fish due to the fact that goldfish and tropical fish need different water temperatures. I would suggest with cichilds but be aware they may get aggressive. Hope you're tank looks nice
