Thats to overstocked I'd say at least 30 gallons and 10 for each added after
so for you I'd say maybe 55 gallons for an oranda a black moor and the white clouds and yes two filters would be better as goldfish produce lots of waste

fancy goldfish (orandas, black moors, etc) get very large (at least 6-7 inches as adults) and need a rather larger tank than your 90 litre. A good guide for fancy goldfish is a 20 gallon tank for a single small goldfish (i.e. a baby) and upgrade to a 30 gallon once it starts to grow (at about 4-5 inches). You'd need at least 10-15 gallons more for each additional goldfish. This oly works for fancy goldfish, not pond goldfish!

Shops often say that you can have lots of goldfish in a tank because a) goldfish are cheap and they don't really care about them b) goldfish are popular so they want to sell as many as they can c) they don't really understand much about goldfish because they rarely see them full grown.

If you want 2-3 fancy goldfish, invest in a 40-50 gallon tank.
