Hey guys, I'm new here and to the whole aquarium thing. My current setup is this. I have a 20 gallon tank with three zebra danios in it. Have a couple of water lettuce, two real plants, three planted ones that haven't sprouted yet, and a couple of plastic plants. The zanios are of different sizes and so the smallest one has gotten really thin. Right now he won't even eat. I asked my fiancée to isolate him to a 1 gallon hospital tank. He still swims well, with the others he hid a lot, and would only take tiny bites off the flakes. This morning though he was completely uninterested. I think it is stress, since the other two pick on him, but he looks thin and pale and I want him to recover. Someone please help :(!

i keep danios. they are great. the problem is that you need at least 4. this is because the picking on is distributed. it sounds bad. i have had this problem before. you need 4 to 6 danbios in a tank. and if that does not work put new species like leopard danios. the tank will lokk fine and the fish will get better and will get less aggresive.

Well the reason why there are only three is because my new tank is only a week old. I suspect that danio wasn't all that healthy in the beginning, and there is also this tiny lump on his lower lip. Right now he is in some sort of breeding divider which isolates him from the other fish. My fiancée nor I can do anything about it right now because we're at work (I'm at break now), and won't arrive home til late at night... We'll see if we can treat for internal parasites, at the same time try some different foods, maybe frozen, I don't know what to do and I don't seem to find a good answer anywhere I look. I really want him to get better... don't want any fish dying on me in a week :(

New development

Okay so upon further study of the fish, we have isolated him within the tank, and he seems to want to eat, but is unable to... he grabs the food, chews it, and spits it back out, or he grabs it and releases it again. Does anyone have a clue on what is going on?

It's getting worse

Hey guys, my fish now doesn't eat at all no matter what we try to feed it. He's been isolated to a one gallon psychedelic tank (looks like what the fish would see in the 60's...) anyways, anything I can do to make him eat? Two more things, he has a tiny growth below his lower lip and I went to Preuss Pets yesterday (a very awesome pet shop around here, a lot better than the chains..) and they, for free, gave me a mix of pellets, with a little bit of garlic guard, and coated them with fusion. It was supposed to take care of his lack of appetite and at the same time, resolve some internal problems he might have. He hasn't eaten it, not even tried. He doesn't rise to the surface anymore for anything that's floating. Anyone know what to do at this point?

Okay this a not going well. but take breaths. he might be getting bladder diesiese. they will begin to float to the top and will be not able to swim. but you could stop this with a huge 50% water change. the change of water and bacteria could help. tell me when you do this. ill help you with all the Knowledge i have.
We can do this.:-D

Well we changed him to the hospital tank yesterday. He CAN float to the top, if I try to catch him with a net, he swims all kinds of places, but he still seems lethargic when left alone. His swimming seems stable and controlled still. There has to be something I can use to make him eat. Also as I said in my previous posts... when he DID try to eat, it seems as if he has difficulty doing so..

And thanks fishlover
Alright. get some tweezers. try to feed him frozen bloodworms. not freeze dried. frozen. they work the best. i have used it on danios and african dwarf frogs. they love it. with tweezers you can get to him and feed him personnly.

Recommendations from Preuss Pets

Hey, I took him to a pet shop earlier. They have a local fish vet that is in charge of their fish care. He even breeds betta which they sell. They gave me some live blackworms... (they look kinda gross....). He said that he is still suffering from some submission problem.. He says that the reason why he nibbles a bit or has food in his mouth and spits it out is because he feels threatened by the others... and it can go on for a week... I will try to get the worms as close to him as possible... but they're wriggling right now in my fridge.... all clumped up in a ball.....

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.
