Fish Have White Needles Growing Near Fins

Hi,

I recently noticed my fish have gotten sick.

Two or three started to have these needles/spikes begin to grow near where their fins are located. The needles are greater than 1 inch in size, but I'd say as wide as a needle/tooth pick.

I've already done a Methylene Blue dip, but I don't think this is helping.

The only other medicine I have for them is Malachite Green.

Does anyone know what this sickness is and how to treat it?

Thanks

 

Do you have any pictures of this? That would help in ID'ing it.

 

Please send pics. It's either an external parasite or a fungus in most likelihood but we need pics before diagnosis.

 

Ok, here are a few of the fish.

On the tetra, on its top fin you will notice a needle pricking out. I was thinking of just pulling it off the fish if you guys think its a good idea.

Otherwise, I just bathed em' in a .010 ppm Malachite Green bath for ten minutes, rinsed and put them back in the tank.

Will do a 30% water change in a sec.

If you need better photo's or clearer, let me know which. The fish are a bit hard to photo-op right now since they are stressed from the baths.

 

There's a parasite called "anchor worm. "

Kinda looks like that in the last two pics.

 

Do these white lines end in two points? If so, I would say it's anchor worms! They are quite common for an external parasite, and you just remove them by hand or with tweezors.

They are only brought in from other fish or aquariums, did you add anything new to the tank before this started happening?

 

I did. I purchased about 10 since they were on sale. I'll go ahead and remove it by hand and hope the others survive the ich(k) / fin rotting.

Thanks

You should always quarantine new fish before adding them to your aquarium, or things like this could happen.

I'm confused, this is neither ich nor fin rot, are there other issues with your tank as well?

Yeah, I posted a few photo's of other fish, one which has it's rear tail fin rotting and then ich (white spots) on other fish.

 

These poor fish had anchor worm's attached to them. I pulled off 2 from different fish and hope they will pull through.

I read K Perm. is helpful. Anyone know where to get some for cheap? Don't need lots.

Thx

 

I don't know I'm afraid, mostly because I live in England!

What are your tank parameters, stocking levels, tank size, ph and temperature! It's unusual to have this many issues without some underlying cause.

 

Since they're newer fish that were added in a large group, I'm going to theorize that there was an ammonia spike in the tank.

The new fish brought in diseases and parasites, which were able to take over the both the new and old fish thanks to the ammonia weakening their immune systems.

That's why it's very important to quarantine, no matter how much you want to see your new fish in the display tank.
