How many fancy golfish can you fit in a 90 litre tank?

Adult size? Approx 1.

You could keep several smaller ones for maybe 12 months, as long as you are OK to re-home the others as they grow.

60 liters is approximately 15 gallons water potential. pondering how grimy goldfish ger, you may choose for to have one small fancy goldfish (around bodies no longer in many situations happening comets) in there, probable 2 in case you're making plans on upgrading in the year yet i'm guessing you're investment is going previous a non everlasting tank. you're extra advantageous off attempting a tropical tank. in simple terms upload the heater and then perhaps choose for some neon tetras in there with a snail. i had to function that the different poster above's remark on "one inch in line with gallon rule" would not prepare to goldfish. Why it loosely applies to many small tropicals, goldfish are nearer to 2 gallons/inch of length. So in different phrases, a single fancy oranda who gets 5 inches desires a 60 liter tank by myself, and it truly is minimum because of the fact it is going to recommend no rocks , decorations, etc. lots truly relies upon on the species you have become. The inch a gallon rule basically provides a undemanding theory of what's going to slot on your tank , then you definately could do to further study for existence form, group sizes, etc.
