goldfish noob

[Thunderloon]

you can do seven and two guppies in a ten gallon

or one female betta and six and two guppies (six fem two male)

don't do male betta and guppies, male betta and just about anything pretty is a no-no, they're flaming bulls

Common Goldfish need 50 gallons EACH. They grow HUGE!
Fancy Goldfish need 20 gallons for one and an extra 10 gallons for each additional fancy goldfish.

Guppies need at least a 10 gallon fish tank.

A Betta can live in a 2.5 gallon (preferably) filtered and (definitely) heated tank.

Yeah just to clarify the common goldfish thing, we used to have two common goldfish (goldie and fin) in a 200 gallon tank and they died two years ago, which means they lived for 21 years. Goldie died of old age and Fin died of an internal parasite, they were both 14 inches long (Goldie was slightly bigger at 14.5 inches).
