Zebra Danio problems

[tttnjfttt]

One of my zebra danios is acting wierd. He is hanging out in one spot at the bottom of the tank. He is still floating, not laying on the sand. He did not eat this morning. Physical apearence - the onlything out of the norm I am seeing some lighter spots on him, like he's lost his coloring. They aren't raised, don't look like open sores, etc. He is also the smallest of my danios and fairly thin. I think he is about a year old (atleast in my possession).

Water chemistry - ammonia: 0, nitrite: .25-.5, pH: 7.4 (I am working on the nitrite at the moment)

Other possible influencing factors: Two days ago, I found one of my tiger barbs had an open sore above his mouth. Not sure of the actual cause, but I am suspecting it was from a fight, but he is in the hospital tank (my ONLY hospital tank) at the moment until I am sure it is not an ulcer and bacterial infection.

Anything else that might help: the rest of the fish don't seem too affected. The danios are wandering around the tank, the tiger barbs are busy chasing each other, everyone else ate like pigs today.

Going pale is a sign of stress where are the lighter spots on him, you have a high nitrite reading some water changes are needed.

 

[tttnjfttt]

Yup, that one is in progress.

UPDATE: This fish is still in hiding and not really moving. He is now in a cave where I really can't see him. I don't think the nitrites are the sole cause of this, as the other fish are still active and eating. Is there anything else I can do?

symptoms
Individual fish stay apart from others. Breathing is normal. They may refuse food. They may have "cloudy" or grey areas on the skin. There are no other physical signs.

possible causes
1) Fish may be suffering from a parasite problem.

2) There could be internal disease problems

3) Early stage of systemic bacterial infection. Isolate and observe

Ok, I have him isolated in a 5 gal bucket which is about 3/5 full. when I was finally able to look at him from a top down view, this poor little guy is all skin and bones. He has no meat on him, and no, i'm not thinking dinner. I offered him some food to make sure he wasn't just getting bullied, but anything he put in his mouth he spit back out. So I think I will go ahead and treat with primafix and salt.

Also, the only heater that I can spare right now is a 10 gal heater. can I safely operate this in the 3 gal of water?

 

[tttnjfttt]

He still won't take any food and is VERY VERY VERY thin. Literally skin and bones. Still slightly discollored, and possibly a little more active now that he is isolated. Should I do anything else besides primafix? It says its good for internal bacterial infections, but i'm not sure if it is parasites or not.

 

[WILDER]

Keep him quarantined as he sounds like he could have fish tb, what does it look like when the fish goes to the toilet, is his anus red and inflamed, anything prutruding from the anus.

 

[tttnjfttt]

I haven't seen this fish go to the bathroom, nothing in his watre either. Nothing hanging out of his rear, and it isn't red and inflamed either.

 

[WILDER]

I would try him with an internal parasite med like clout being skinny is internal parasites or fish tb.

 

[tttnjfttt]

Do i need to worry about my other fish in that tank?

 

[WILDER]

Yes as if one has them you can bet another one does, see if you notice an improvement with the med on the sick fish, but it might be to late as if he does have he is infested with them.

I am not the writer of this article.


just wanted to mention there is a better form of levamisole available. It
should be near the oblets available for sheep, and is a packet of powder,
called Tramisol. I recall it may have been something like 11-12 G to one
packet. It's somewhat difficult to break down into small portions for the
tanks, but easier in the long run than the oblets, I think. I bought one
packet and treated all my tanks 2x. This was for approximately 100 G. I
think I may have used 5-10 mg./l. There was no discomfort noted in any of the
fish during treatment, or after.
