alright. thats good. always keep live food. its good for them to change their diet. very good. well tell me when he gets better.

My 10 gallon
----------------
4 Zebra Danios(danio rerio)
2 Amazon Swords(Live Plants)

How long ago was this tank set up? How is the water? what are current readings for pH, Ammonia, Nitrite and Nitrate?

Danios are schoolers and prefer much larger groups than either of you has. In large schools, no one gets singled out and bullied, but three or four just won't create the right setting-- much better to have a dozen or two. I also prefer that they be housed in longer tanks: twenty long (30") or even longer since their swimming style is not stop.

The White spot near the mouth sounds ominous as does the refusal to eat. Either could be indicative of bacterial or fungal infection. When was the last time you did a partial water change?

I would be careful with live blackworms: similar to tubifex worms these originate in raw sewage and need to be cleaned well before feeding. In my experience small leeches are also sometimes present in these cultures.

Fish health begins with good water. Find out (through a water test) what you're dealing with and go from there.

I did do a water test today. The pH was at around 7.4, nitrate, nitrite and ammonia levels are 0, GH is 9 and KH is 5. These levels are fine for it. There's a biologist that works at that pet store and so he looked at it, and concluded that it was just stressed by getting picked on so much, he still has color, he's just very thin. we bought more danios to increase the school size. The tank was set up 9 days ago. The zebra danio in question has been isolated until he gets better.

Nine days ago means this tank hasn't cycled. You will imminently see a spike in ammonia that will rise for several days. Following that, nitrite will begin to increase as Ammonia levels fall. Finally, at around 4 to5 weeks, the nitrate will taper down to levels that are safe, and it is at that point most people begin to stock their tanks, slowly and gradually--a couple fish at a time.

I agree with the assessment of the LFS regarding the small fish and aggression, but worry that ammonia and nitrite will be punishing for your other fish.

Monitor the water, do frequent small water changes, add prime as needed to de-toxify the ammonia and nitrite.

This won't be easy. It is much simpler to wait until the tank has cycled using a little plain ammonia to start the cycle.

*sigh* I was worried about that.. The tank is planted so I'm hoping that the ammonia spike is not as severe...

Possibly. I have noticed that many people on this site tend to justify early addition of fish to a tank because you have live plants.

But the plants have to be pretty abundant and they have to be lit well enough to actively use up the nitrogenous wastes. I mean, it's a pretty vague balance to try to hit, and from what I have read, people are playing rather fast and loose with this "soft cycle" approach to circumvent the need to wait. At all. Planting up a 55 gallon with tons of lush greenery and adding a few neons isn't the same as adding a ten inch oscar to a 55 with a little hornwort garnish around its neck!

Just monitor your water often with tests for Ammonia and Nitrite and hope for the best. Good luck.

RIP Runt :(

Well this post is just to inform you that my little zebra danio, the one that wouldn't eat, was found dead this morning in his hospital tank. I wish I could've done more for the little guy. I'm going to take him to the LFS just to make sure he didn't have some underlying condition. I want to put him in the fridge until then. What is the best way to preserve a fish short term, in the fridge with water or without water? I have a stash of blackworms which I really want to get rid off too... just flush them down???

Unless they look appetizing to you!

Sorry about runt. Doubtful a PM will unveil anything meaniful. I suspect bullying and his small size contributed. Freeze the fish or keep in very cold refrigerator.

Good luck going forward!
Randy

ANOTHER danio won't eat!!! He looks fine except for the fact that... eh won't eat for some reason... he's been isolated already.. this time it's a golden danio. I am defrosting some blood worms to attempt to feed him later.

At 9 days you're having water issues, negatively impacting your fish. Do daily water changes with Prime. Test your water daily.

Consider the needs of your fish before acting on your desires.
