Fish diseases

Ok heres whats going on. Ive had 3 zebra danios die on me. THey showed symptoms one day and the next they are dead. Today 2 more have symptoms of an internal paracite or fish tuburculosis. My otos died of suspected dropsy.

What medication should i use, i have 1 oto left (its scaleless) so what do i do? I dont want my rams to catch it and i dont want any more danios to die

I will be treating the whole tank since im pretty sure the disease is somewhere in there

I have standard ich medication, it has malachalite green in it, dont know if that helps anyone

Water params

ammonia: 0
nitrite: 0
Nitrate: 10
Ph: 7.4-7.6 (the test results show somewhere in between those)

If those fish (Danios) do have the symptoms that you have explained, and you think they might have an internal parasite then treat with isoniazid, kanamycin and vitamin B6. If you think they might have tuberculosis, then treat with gentamycin Sulfate or oxolinic acid.

You should treat your Oto with oxytetracycline hydrochloride powder for about ten days. 25 grams, which is about what you need, would cost probably somewhere around $15.

Because you may have two or three different diseases in one tank, it would be my recommendation to transfer the diagnosed fish to seperate tanks when treating since some antibiotics don't mix well. Always perform a 25% water change before each treatment.

Malachite green treats mostly just protozoans (thus effective on Ich).

well none of my fish have dropsy now, one already died of suspected dropsy, no other fish are showing signs.

The symptoms are
in activity
hides a lot
after a few weeks of the symptoms the inability to eat

There eating now (i just fed them) and they've regained a bit of there nippy activity. I hope i detected the disease early so the treatment can help.

My question is is it tuburculosis or internal paracite

there are no other symptoms and aside from what i told you they have very normal color and there fins are outstretched.

really sorry to hear about your fish. im pretty new to fishkeeping so whatever information i have is just from searching online - feel pretty bad that nobody has replied thoguh since i got a load of replies for my posts so the best i can do after having a search for you is that internal parasites are rare amongst aquarium fish and are more likely to be present if you have snails in the tank along with the fish, and if your tank is crowded, if you do then perhaps thats the problem. inactivity is also a symptom of internal parasites which you mentioned. it also said that often when the fish have internal parasites then you can actually see them hanging out out the fishes bum so if you havent looked for that it might be helpful. i also found that a very general way of treating sick fish was by using a "salt bath" which wont damage the "good bacteria" if youre worried about that but i think thats a bit besides the point. tbh id be more worried that it would stress the fish since theyre freshwater fish.

As far as TB is concerned, here is a short paragraph I found that hopefully will be useful for you:

For those of you without a histology lab at your disposal, the symptoms of Fish TB are usually wasting, lesions on the body, skeletal deformities (a few of mine developed curved spines), and loss of scales and coloration. This is a relentless disease. I have read that it is not considered treatable; however, I figured my 15-year-old Raphael catfish deserved a chance. Against the advice of my veterinarian, I have not euthanized my afflicted fish (over half died shortly after the disease bloomed anyway). The typical drugs for treating fish are the same as for humans, most often a combination of two drugs administered for at least three months. Currently I am trying Kanacyn (Kanamycin). Once the fish became emaciated I had no luck saving them. Traditional tricks for curing diseased fish, such as adding salt and raising the temperature, are ineffective and in the case of the raising temperature may even be detrimental. The bacteria grow better in warmer water; their optimum temperature is 30°C. They have no problem with salt either; they can infect saltwater fish as well as freshwater.

Like i said though, im pretty new to fishkeeping so this is all probably old news to you but its the best i can do im afraid. i hope your fish are alright

ok my fish do have a tiny bit of a curved spine but they dont have any loss of color or loss of scales, im guessing internal paracite now. They ate again today so they wont have the chance of starving to death. My tank is pretty under-stocked, 4, 3/4 inch fish, 1, .5 inch fish and 2, 1.5 inch fish, so i dont think overcrowding is an issue. I will check there butts to see if anything is hanging off them. What medicine should i buy and how much salt should i use. I have scaleless fish in that tank so i dont want to be causing damage to the scaleless. Also copper treatment is out of the question since i have shrimp and this tank will become a saltwater reef tank one day.

Yes by the looks of it there is something hanging from her butt. I think blue recommended a medicine for this, thanks for your help

definitely seems like internal parasites then so probably best to try the medicine blue recommonded then.

a link for the salt bath i was talking about is: http://www.fishdoc.co.uk/treatments/salt.htm

though it does say that this is best for external parasites of bacterial infections but if nothing esle works then youre as well to give it a go. the link gives you the amounts of salt and the amount of time you should use it for.

hope your fish are alright. post a wee reply afterwards to let us know how they get on

sorry i meant to say as well that since youre taking the fish out the tank into a different container for the salt bath then you wouldnt need to worry about damaging your scaleless fish. but like i said go with blues suggestion first since it does definitely seem like internal parasites

it was from a previous thread that i made, i remember this stuff. It was when my first danio had a problem a bit different from this but was diagnosed the same way, the other danio didnt eat, had a really arched back, and layed on the gravel with the gills still moving. This one is a bit different so i posted another one to see if they are different disease, apparantly there both the same.

Although i hoped my other fish wont catch it, it seems like one of my bolivian ram is getting the same symptoms as the otehr fish :(
