Danios and Golden White Clouds

I don't have any experience with them, yet. I will be getting some soon though, both of the types you listed. Both of them are danios and should be no problem being kept together. What size are they ?

 

I have a Danio in a 5 gallon tank that I used to help get it cycled. Its a really hardy fish and doesn't seem to be aggressive. I plan on putting a few more in there and then putting my Swordtail babies in there when they come. My understanding is that they are pretty peaceful fish. Try putting a few more in there. They should start schooling and leave your other fish alone...

 

Danio's act like bullies at times. Especially when their numbers are low. Harmless really but yes, it can stress out other fishies. It's best to keep at least 4-6 in a group. This way they will mostly focus on themselves.

 

How many of each do you have in the tank ?

 

Sorry, I now see you listed how many in your first post. If the Zebras are chasing the White Clouds I would suggest getting 2-3 more of those, not the Zebras.

 

Even if you get more white clouds, the zebra's will still chase them. If adding any others, you should add at least two more zebra's.

 

Why add more of the fish that is causing the aggression ? Increasing the number of White Clouds should make them feel more secure and cut down on the Zebra aggression.

I do agree that there should be more Zebras but not at this time.

 

What's your logic in that

 

The issue is with danios not having the numbers to establish a "pecking order". Since there are only a couple to begin with, they don't have interest in each other so they are going to go after whatever they can find. This is why you establish the colony with larger numbers so they keep interest on themselves.

Granted, it doesn't completely stop the chasing as that is just normal behavior, but it will significantly reduce it towards other species.

 

Correct, the numbers of each are too low. At this point though the Zebras basically "own" the tank. Increasing the numbers of White Clouds should put the Zebras in their place by seeing they're clearly outnumbered. Placing more Zebras in the tank will only make them feel stronger.

 

Sry...I have to respectfully disagree about the strength comment. They will have too much interest in themselves to pay much never mind to their tank mates. This is from experience as I currently have four long fins. They are too busy chasing each other around to worry about the barbs and minows in the tank with them.

 

You can disagree, that's fine. It's just two different views on the situation.

 

James0816 I understand what you're saying but I don't see the logic in that either

 

np...its not logic...its the nature of the species of fish.

 

It's the nature of schooling fish to not pick on a smaller group of a different species? That's new to me

 

Exactly. I'm not really into fish, but this is everyday logic. Weaker fish will be stronger in larger numbers and strong fish will be weaker in smaller packs. It's very simple.

 

It's the nature of the zebra danio not schooling fish in general. They are a very active/hyperactive fish. Their nature is to zip all around the place. When you only have one or two in a tank with other species, they tend to chase and/or stress them out since there are not more of their numbers to focus on each other. In this example, the danio is not going to care that there are more minows than them, they are still going to chase them. The more minows...the more to chase. ;o) However, when you have a school of zebra's (4+), they will 90+% of the time focus mainly on themselves thus ignoring the other mates in the tank. It's how the zebra is. Nothing wrong with it...it's just his nature.
