Colorful fish compatible with ryukin goldfish?
« on: January 11, 2012, 11:12:11 PM »

I have decided to create a 40 gallon community tank with 2 ryukin goldfish (or possibly two fantail or veiltail goldfish, instead). By searching the web, I know that White Cloud Mountain Minnows and some sort of danios is compatible with goldfish. But the thing is, I like having easily identifiable fish with names. For example, it's easy to tell fish like bettas apart, but it's not with minnows because they all practically look the same!

Anyways, Does anyone know any 'easily identifiable' fish that is compatible with ryukin goldfish? I like colorful fish, that I know won't be bait for growing goldfish.

Like a blue, chocolate or calico goldfish Smiley
You should really avoid mixing smaller fish with goldfish. I have kept Mollies together with goldfish though, so if you feel like having a boy and a girl, you could easily tell the difference since the girl would grow bigger.

But still, I do find that my little bunch of 8 are very happy swimming around together compared to the community tank with only two goldfish and a bunch of mollies Smiley

Oh, thanks for the answer. So, what do you think about 4 ryukins in an almost 45 gallon tank (90cm L*45cm W*40cm H) with a 50 gallon filter? Do you think this is a good idea/should I change it to 3 goldfish instead? If so, how often should I clean it?

Ryukins get huge- up to 2lbs. I'd say three but I prefer to understock. Four would be fine. I'd also suggest getting a larger filter, do you know the GPH? Sometimes a filter labeled for 50 gals only does 100Gph. In any case you should still do a weekly water change no matter how great your filter is. I do 60-80% on all tanks every week.

Hi Sparkly puffball,

As Cheri pointed out you will need a larger filter. Goldfish are extremely messy and so usually the recommendation is for the filter to be able to turn over the tank volume 10x in an hour, so usually if a tank is rated say 30 gallons, then a 300 gallon per hour filter would be best.
External filters are usually the best thing for goldfish as they can hold a lot of media for bacteria, and can deal with the waste from goldfish. But you could always run an external filter alongside an internal filter if you prefer. But overall with filtration you'll want something that can do 450 gph Smiley

You can have four goldfish in the tank, IF you are prepared to change out half the water and vacuum the gravel every week religiously! Smiley Here's a thread explaining proper tank maintenance: (Link is not visible to guests. Please register to view.)

For a 40-45 gallon tank you'll want a filter rated for a tank twice the size, so you should be on the lookout for a filter rated for an 80-90 gallon or one that filters 400-450gph Smiley

Hi cheri alexander,
I was planning on getting an Aquaclear 50 Power filter which pumps up to 200 GPH, but know that you guys say, I am now going to get an Aquaclear 110 Power filter which pumps up to 500 GPH.
