Well, I'm thinking of getting some more fish. I will be purchasing a new tank for these fish probably a 20 gal (75 litres). I would really like to get a telescope and Oranda but I have heard that Oranda grow really big

If I dont get an Oranda I would probably get a Pearlscale unless they grow big too and then I'd have to find a new fish :\

Is there anything I should know before purchasing the fish like : how big they grow, feeding them (seperately or together), and their needs

This would really help me heaps ^_^

Hi there

Well you need 10 gallons per fancy goldfish so you could put two in a 20 gallon tank, as long as you have really good filtration and keep up on the water changes. If I were you I'd start with one fish until the tank is cycled.

As for the fish themselves, yes, orandas can grow very large. Pearlscales don't get quite as big. Usually you can feed all fancies together, just watch them to make sure everyone gets their fair share.

Chrissy Bee said it all lol you should befine with 2 fancy goldfish in a 20 gallon remember to do weekly waterchange and have great filter system and air system. Pearlscale is fun bc they ...get very.....very...round...
