Guppies Bullied By Danio's?? Help!

I have a new tank, a 5 gal. about 3 weeks old. pH tested well, and I do 30% water changes every two weeks or so.

The tanks inhabitants are 3 male cory cats, 3 Long finned danios, and 2 fan-tailed guppies. ALL of the fish are well under an inch and mostly stay out of each other's way. I am aware that the tank may be a bit overcrowded, but it seems that none of the fish have too big of an issue. Moreover, I have a small live plant, and a small piece of petrified wood with granite on top to create a little "hut". Plenty of cosy hiding spots.

Now, the issue has come with the addition of the guppies. one guppy, with a larger tail, has had very small nips at the ends of his tail since I bought him. The other however, had his tail split right down the middle within days of his purchase. Then, last night I caught the slightly larger the Danios nipping at his tail. The poor guppy has almost no tail left! Now he has secluded himself behind the filter while the other guppy is being quite social.

For now, I have placed the "mean" danio in a small square glass container with the water from the tank. I will change the water daily and feed him as normal, I just don't want the poor guppy to lose his entire tail!

At this point, I'm not sure what to do. I am aware that the danio's should have more space, but what do I do with them! And if I could keep all the fish, what could I do to prevent this scenario from repeating itself? Alternatively, I would prefer to relocate the guppies, but how would I go about doing this?

 

Well, get a larger aquarium, preferably at least 20 gallons. All these problems are occurring because of the lack of space.
Danios need at least 20 gallons.
Corydoras need at least a 20 tall.
Guppies need at least a 10 gallon.

 

Also the danios and the cories are a schooling fish and should be kept 6 or more. I didn't see a goldfish mentioned but I could of missed that. Goldfish need much much larger tanks.

Oops read it wrong.

 

You also need to be doing more water changes. The danio could just be stressed from poor water quality. Ph doesn't really matter - you need to be testing for ammonia, nitrites and nitrates. Especially while your tank is cycling. You should be doing 50% water changes every few days until you can get a test kit.

I got the test strips and nitrate read as clear as did ammonia. Currently, without ability to get a larger aquarium, I am really wondering if I should put the danio back in right now. I'm not sure what would be better, keeping the guppy safe while stressing the danio, or risking the last of the guppys tail for the health of the other fish.

Try rehoming everything and get a Betta

 

second that^

 

If you can't provide them with a suitable long term housing solution, I strongly suggest you rehome all your fish and restock with something more suitable. Your problems will only increase from here on in.

 

Bettas are super fun fish You're only going to have more problems with this current stock.

 

I have danios and guppies and they get on fine. They chase each other, no-one is being picked on.
However, there can always be a rogue fish, I had a rogue WCMM, he was really tiny too.
See if the LFS will take the guppies back but they may not want damaged fish back. They might take the danios back. I don't know how to go about rehoming fish, I personally would always get my fish from a store unless it's from a breeder.
If the guppies are that badly beat up, you could shift them into another tank/container. A lot of floating plants will suck up ammonia. Guppies love floating plants.

Thanks so much for the help guys. I've been saving up a little money, and I think i'm getting a 20 gal. I'm already using an aqua clear 20, and I have enough gravel and plants to occupy the new space. Hopefully everyone will be happy . I'll most likely make the change within the next three or four days (I'm in high school so time is tight) and I may continue to keep the guppies in my 5 gal doing daily water changes until they are more healthy.

My current tank mates are 3 Cory's, 3 danios, and 2 guppies. I had a betta a long time ago, but I'm looking for a more serious tank that can actually show some diversity. I know I want to get a pleco at some point, but is 20 enough space? If not, what kind of shrimp/snails should I get for their new home? I'm open to any recommendations on fish, or even just transferring what I have and getting a couple snails. Or even increase the school sizes of the fish I have a bit? Otherwise, I already have one floating plant, but I'm new to larger tank sizes so I'm really just wondering what would provide the best environment for my fish! Again, thanks so much for all the help guys!
