I know goldfish are cold water. But I noticed they do fine in warm water. I am actually saving up for a 55 gallon tank by selling my 2 20 gallons. My filtration is an aquaclear 70.Nice tank and good start but a few things.
Gold fish are cold water fish..that being a commit gold fish it will get over a foot long. they are large fish that need a 55g tank.
the rest of your fish from what i can see are fine. but I highly recommend re homing that gold fish or getting it a larger tank.
what is your filtration?
and how often do you do water changes?
How big of a tank would you recommend for a comet goldfish and possibly a shubunkin goldfish?opcorn:
Keep in mind a healthy comet will eventually outgrow a 55g anyways. There's a reason they are considered to be pond fish.
Get some more turquoise rainbows and corys when you upgrade...they should be in groups.
Otherwise, it's a neat setup.
