Is the HOB filtration I have okay for keeping four (small as of right now, but definitely growing) Fancy Goldies of the Red Cap Oranda, Black (now Gold) Moor and Common Fantail variety in a 60 gallon? I'm running an Aqueon QuietFlow 55, good for some 325 gallons per hour of turnover, plus an AquaClear 110, good for some 500 rated gallons per hour of turnover, which gives me a total of more than 800GPH; I totally understand the theory behind the fact that once media pieces are introduced to HOBs (and canisters I believe too) this "gallon per hour" rating can be reduced somewhat, but I just wanted to know if off the cuff, this filtration is adequate...

I'm also running two 18" bubble bars powered by Top Fin's biggest air pump, the AIR-8000 model, and these bars are SPITTING out the bubbles...so oxygen and Co2 exchange isn't a problem...

Also -- am I at my stocking limit for a 60 gallon with Fancy Goldies? As I stated, right now I have four, two of which are juviniles on the small side and two -- a maturing Red Cap Oranda and a Black Moor -- that are larger than small, but I'd say not quite "medium" sized either. Should I just let these guys mature in this tank without adding any additional fish? I know the Fancies are known to get really big...

I know I had some more questions about these beautiful, often mistreated and misunderstood creatures of the Orient...but I can't recall at this very moment; I'll update the thread as I remember them!

Thank you, everyone!
