Danio + Guppies?

[SusieJG]

Does anyone have any experience with a tank containing both long finned zebra danios and guppies? If so, did the setup work?

 

[The-Wolf]

Yes, I have had that sey up.
The Longfinned Zebra danios are not as nippy as the "normal" ones.
I had the same number of ZD's to guppies and they were ok untill
I lost some guppies, then the ZD's started nipping the fins of the remaining ones.
I currently have my guppies with giant, bengal and moustached danios without any problems.
HTH.

I have a 30 g tank with maybe almost 100 (actually less now, but I haven't tried to count lately) guppies and Endlers' and hybrids. I originally intended for this to be a comunity tank, so I added 4 long finned danios a few months ago. At first the danios seemed to be trying to school with the guppies, but it didn't take them too long to find each other. they play follow the leader and hide and seek and ring around the seashell a lot, but when it's feeding time it's every fish for itself and they don't care where the other danios are. I've noticed very little interaction of any kind between the danios and any of the other fish. maybe sometimes a small gupler appears interested in a bigger danio, but the danios dart around so fast, it's easier for the guppies to chase each other.

I it just me or does that not seem way, way, way overstocked?

Don't worry - You can easily fit that many fish in a 30G - as long as you take all the water out.

is that serious - 100 fish in one tank. Maybe you put the tank size in wrong?

 

[wrs]

it sounds like fry. there is NO WAY 100 fish could fit in a 30 gallon. 30at most. But that still minght be overstocking.

Looks like I've inadvertently changed the subject.
Actually I think it may be a bit over stocked, but they are all small fish and all but 2 or 3 were fry when they first went in. I never did an official count , but one of my guppies had 25 fry that i counted and then there seemed to be about twice as many the next day and she had broods about the same size 4 months in a row, so if i estimate 50 per brood, and figure 1/2 of them went to the boy tank when i separated genders, that gives me a rough estimate of 100. I still want to sell some to a LFS, but for a while I was reluctant because they kept getting sick. Now I think they mitht have been sick less if I had sold them earlier. but my mom keeps pointing out that they look more crowded in the store tanks. I have given away a few, but more have died, possibly due to overcrowding.

Shops have very sofisticated filering systems, un less you want to spend
thousands on the same system you will never match the capacity of a shop tank healthily.
In addition the fish in shop tanks are rarely there for more than a week or so.

Back to the original question, as I have said in my frst post, it can be done with equal amounts of the two species.

Wolf is right I loved the system my lfs had it's not that large even ....After a little research I estimated about 3,000 dollars even after I did all the piping exct. myself with pvc !! your tank is too overstocked ...... You said they were dying from sickness I doubt that is it ...... You are overstocked And my guess is within a month you will be down too 50 or less fish

 

[guppler]

well, as I said, I haven't counted lately, but It's already been over a year and they weren't dying off in huge numbers. After I lost 8 female guppies in one dayI had all my tanks' water tested, and they only said the girl tanks had nitrate and amonia problems at that time. In fact, they don't even look crowded. I think I only have 3 or 4 left that are regular guppy size. The rest are smaller, and the danios all seem healthy. I do try to keep it clean and take some of the fish out sometimes if they have specific symptoms that others don't have or to visit girls, which hasn't resulted in any new fry yet.

Quickest way to keep guppy fry numbers down to the fastest and smartest survivors only, is to put some neons, blacklights or glowlights in the tank. They LOVE guppy fry. Particularly with ketchup. Seriously, natural predation works wonders, that and keeping the male guppies in a different tank!

I admit that sounds like a vastly overstocked tank. Granted, live plants seem to help in letting you keep more fish but w-o-w, that seems like a lot. Maybe with less fish in there they'd grow bigger? Just wondering. I am amazed that you can keep danios with any fish. We had right problems up here with that, they went after everything else and nipped. Any minimum danio number recommended so they behave themselves and play nice with only each other?

the minimum nubers of danio is 5, but the more the merrier
